![]() It is synthesized from DNA and is piled up in the nucleolus. It is also present in some amounts in the ribosomes of nucleus, chromatin, and nucleolus. Nucleic acid contains sugar, nitrogenous bases, phosphate, and is a very complex organic acid.ĭNA (Deoxyribonucleic acid) especially found in the cytoplasm in soluble form and is called soluble RNA. It is primarily nucleoprotein, made up of nucleic acid and basic protein histone. At the time of cell division, the chromatin threads isolated from one another become thicker or massive and smaller and are now termed as chromosomes. Chromatin threads are associated with one another and form a network called chromatin reticulum. On the other hand, euchromatin is a mild, less condensed organization of chromatin, which is found amply in a transcribing cell. The heterochromatin is a highly condensed, transcriptionally inactive form mostly present adjoining to the nuclear membrane. The chromatin is classified further into heterochromatin and euchromatin based on the functions. The nuclear membrane is made up of lipoproteins, perinuclear space, pores, annuli material, an inner dense lamella.Ĭhromosomes are present in the form of strings of DNA and protein molecules called chromatin. Such nuclear pores are the sites for the exchange of large molecules between the nucleus and cytoplasm. The nucleus gets through the remaining of the cell or the cytoplasm through several openings called nuclear pores. A liquid-filled space or perinuclear space is present between the two layers of a nuclear membrane. The nuclear envelope is connected with the endoplasmic reticulum in such a way that the internal compartment of the nuclear envelope continuous with the lumen of the endoplasmic reticulum. The outer layer of the membrane is combined with the endoplasmic reticulum. ![]() The nuclear membrane is a double-layered system that encloses the elements of the nucleus. Nuclear membrane or envelope or karyotheca The main components of the nuclear structure are discussed below. ![]() The nucleus is similar to the brain in its functions of coordinating all the cell activities. The DNA controls the form, function, and growth of the cell. The envelope helps to maintain the shape of the nucleus and assists in coordinating the flow of the molecules into and out of the nucleus through nuclear pores. Like the cell membrane, the nuclear envelope consists of phospholipids that form a lipid bilayer. The nuclear membrane separates the constituents of the nucleus from the cytoplasm. Nucleoplasm, also called karyoplasm, is the matrix present inside the nucleus. The cell nucleus consists of a nuclear membrane, called the nuclear envelope, nucleoplasm, nucleolus, and chromosomes. Unlike mammalian red blood cells, those of other vertebrates still contain nuclei. Antonie van Leeuwenhoek observes a ‘lumen’, in the nucleus, in the red blood cells of salmon. The nucleus was the first organelle to be discovered or detected. The nucleus is detached from the rest of the cell or the cytoplasm by a nuclear membrane. Some are multinucleate it means it consists of two or more nuclei, for example, slime mould. However, some eukaryotic cells enucleate cells (without a nucleus) for example red blood cells. In general, a eukaryotic cell has the only nucleus. The nucleus is the most prominent organelle as compared to other cell organelles, which account for about 10 percent of the volume of the cell. The structure of the nucleus includes nuclear membrane, chromosomes, nucleoplasm, and nucleolus. It is also responsible for the coordination of genes and gene expression. The nucleus is the control centre of eukaryotic cells. The nucleus is a spherical-shaped organelle that is present in every eukaryotic cell. Likewise, in the plant cell, the nucleus is located more on the periphery due to the large water-filled vacuole in the center of the cell. In an animal cell, the nucleus is located in the central place of the cell. ![]() The nucleus is an organelle that consists of the genetic information for that organism. Likewise, Eukaryotic cells all have their DNA enclosed in the nucleus. The prokaryotes have no nucleolus- the DNA is in the cytoplasm, it can form small circular strands of DNA called plasmids. There are two types of cells one is prokaryotic (bacteria) and the other is eukaryotic (plant, animal, fungi). The Cell provides a structure for the body, takes in nutrients from food and carry out important functions. Cells are the fundamental or key structure of all living organisms. The human body consists of trillions of cells, all with their own particular function. The study of cells is called cell biology. Cells are called the building blocks of life. The cell is the basic and structural, functional, and biological unit of all known living organisms.

Cross, he only brightened when manager Janet Billig told him the show would be remembered as “a career-defining moment.”Įveryone in attendance felt they’d witnessed something special that night, and the wider public was equally convinced when the full MTV Unplugged In New York set was released just seven months after Cobain’s death in April 1994. Spine-chilling and otherworldly, it was an absolutely riveting spectacle to behold and provided the perfect full stop to one of rock’s most transcendent live albums.ĭespite generous applause and exhilaration among his bandmates, Cobain allegedly remained underwhelmed by his performance. Kurt Cobain, however, saved the performance’s most jaw-dropping moment for the final encore, for which he chose the traditional folk tune “Where Did You Sleep Last Night?” With Nirvana following Lead Belly’s arrangement of the song, Cobain performed it with his eyes closed his voice cracking from sheer emotion during the final chorus. ![]() MTV might have bemoaned the omission of “Smells Like Teen Spirit” and “Lithium,” but a compelling “Come As You Are” more than made up for it, while the sparse, acoustic setting merely enhanced the subtleties inherent in the band’s more reflective In Utero material such as “Dumb” and “All Apologies.”Įlsewhere, the setlist found the Seattle stars revisiting their triumphant Nevermind album with choice versions of “Polly,” “On A Plain” and an ominous “Something In The Way.” Arriving midway through the set, this mighty triumvirate was presaged by resonant covers of Scottish indie outfit The Vaselines’ “Jesus Doesn’t Want Me For A Sunbeam” and David Bowie’s “The Man Who Sold The World,” and succeeded by The Meat Puppets’ guest slot, with Nirvana accompanying the Arizona band’s Cris and Curt Kirkwood on quirky renditions of three tracks from their psych-infused Meat Puppets II.Ĭlick to load video “A career-defining moment” Cobain may have requested a funereal stage set decorated with stargazer lilies, black candles, and a crystal chandelier, but his performance was never less than life-affirming.Ĭlick to load video “They hint at where Nirvana could have gone next”Īugmented by touring alumni Pat Smear (guitar) and Lori Goldston (cello), Nirvana eased into a consummate version of Bleach stand-out “About A Girl” and never looked back. However, all the tensions were swept away when Nirvana hit the MTV stage for real on November 18, 1993, filming a performance that would be broadcast a month later, on December 16. “Therefore, everyone was more than a little concerned about the performance.” “There was no joking, no smiles, no fun coming from him,” MTV production manager Jeff Mason recalled in Charles R Cross’ biography, Heavier Than Heaven. MTV was concerned about the lack of hit songs Nirvana proposed to play in their set, while Cobain – who was wracked with nerves and suffering from a recurring stomach complaint – appeared less than enamored during two days of tense, pre-show rehearsals at New York’s Sony Music Studios. ![]() Nirvana finally acquiesced when MTV agreed to them bringing their In Utero touring partners, Arizona alt-rockers The Meat Puppets, along to appear as their special guests. However, the band began to warm to the idea when they recalled that one of their favorite albums – Screaming Trees’ frontman Mark Lanegan’s debut solo album, The Winding Sheet – made a virtue of a similarly intimate approach. Kurt Cobain and his team also had reservations over how well their visceral rock’n’roll would translate in such a stripped-back, low-watt setting. “Most bands would treat them like rock shows – play their hits like it was Madison Square Garden – except with acoustic guitars!” “We’d seen other Unplugged shows and didn’t like many of them,” drummer Dave Grohl later told Rolling Stone. Initially, the Seattle grungestars were in two minds over whether they should even accept their invitation to appear on MTV Unplugged, not least because they felt the program’s format simply wasn’t for them. After a three-year hiatus following a Korn special in 2006, the show was revived in 2009, with most new concerts debuting on MTV.com.“We’d seen other Unplugged shows and didn’t like them” Artists found a way to revisit and reinterpret their songs what their performances lacked in volume, they more than made up for in a more sharply focused energy. It was an idea that yielded some terrific music. ![]() Sure, it had been done before, perhaps most famously by an acoustic-guitar strumming Pete Townsend during a 1979 benefit concert called The Secret Policeman’s Ball, but the idea of placing a musical act on a stage cleared (usually) of any electrically powered instrument or device became the signature concept of an MTV show called Unplugged.

Seriously intermixed, as nanometer-sized formations of Pele’s Tears have been found in the cavities of Pele’s Hair. These occur primarily in Hawaii and are often intermixed with Pele’s Hair. This leaves us with a variety of small, irregularly shaped needles and nodules that are collectively known as Pele’s Tears. They occur when the material thrown from the volcano is cooling on the way down. Apache Tearsĭistinct from Apache’s Tears, Pele’s Tears are an aerodynamically formed obsidian nodule. The following isn’t a 100% comprehensive overview, but it covers the vast majority of unique formations that can be found. There are some rare forms of it out there available in only a few locations that people often try to collect. Not everyone collects obsidian based on the variety. It’s easy to find, rather cheap, and incredibly attractive for something which can seem so simple at first glance. Mahogany obsidian deserves a place on every obsidian collector’s shelf. The latter can take advantage of the patterns to create wonderful knives and arrowheads which are accented by the internal coloration. ![]() It’s used in jewelry, and decorative objects. You’ll sometimes hear this variety referred to as red obsidian, which… isn’t great but it’s better than most of the material sold under that name. This leads to the large, rust-colored bands and spots in the stone. The coloration in mahogany obsidian is thought to come from hematite included in the glass as it cools. These can range from large splashes to more intense and intricate banding depending on the individual sample but it’s another common variety used for more than just jewelry. Mahogany obsidian bears deep red-brown patterns and streaks across the black surface of the material. The careful attention to angle when cutting, and the inherent difficulty of polishing obsidian, can combine to create incredible beauty or destroy the fire entirely. ![]() In an interesting way, fire obsidian is one of the peak challenges of the lapidary arts. It’s usually sold per carat, as opposed to every other variety which is sold by the pound or piece depending on how much work has been put into the rough.įire obsidian is only found in a few places and if there’s anywhere else… people are staying tight-lipped about it. When it’s cut properly, fire obsidian will show an incredible array of bright colors when viewed from the proper angle.įire obsidian’s effect is created through thin-film interference, much like rainbow obsidian, but the material here is ultra-thin layers of magnetite instead of the hedenbergite that causes the colors in rainbow obsidian.įire obsidian is extremely expensive compared to most varieties.

Sheen Obsidianįire Obsidian (credit: Jessa and Mark Anderson/ Flickr)įire obsidian is… something else. There are great places to find it in each state along the Western Coast of the USA, and some great examples also come from Mexico. Rainbow Obsidian is the second most expensive type of obsidian most of the time, but it’s very affordable compared to Fire Obsidian. This effect is caused by thin-film interference, think of it as a solid oil slick effect. This mineral is oriented in the rainbow obsidian and causes light entering the stone to act differently. The cause of this coloration? Nano-rods of hedenbergite. Rainbow obsidian can range from full-facing, incredible pastel colors to a barely visible sheen form an oblique angle. Some of the most striking examples are found in the aptly named Rainbow Mine in the Warner Mounts area. ![]() Rainbow obsidian is a prized material, varying greatly in colors. Before the discovery of fire obsidian, which has a much more intense effect, it was among the most expensive types.
