What are the smallest genomes?

genomes are a code of life - a molecular plan that builds every living organism. The human genome, found in the DNA in the nucleus of the cell, has about 3 billion pairs of amino acid bases and 20,000-25,000 genes coding proteins. This is relatively typical of methazoan organism. The size of the genome does not directly correlates the complexity of the body, but does abstract, especially when comparing the length of the genome between multicellular and unicellular organisms. The parasites have the smallest genomes of any multicellular organism that have undergone a process known as genetic streamlining. Since 2011, he has been the smallest reported genome found outside the organs genome tremblaya , which has only 121 genes, and is found in bacteria found in Mealybugs. Other extremely small genomes include Cansonella Rudia, also known as c. These bacteria are found in insect suction suction suction called bouncy plants lice. Endosymbiont, c. Rudii lives in specialized organs in insects called bacteriomas. They have a mutually beneficial relationship, and the insect body provides nutrients and shelters to bacteria and bacteria give vitamins and amino acids insects.

The second smallest non -real genome is found in nanoarchaeum equitaans , thermophilic archaea found between the hydrothermal holes on the bottom of the Atlantic Ocean DNA around the Central Atlantic Ridge. n. Equitaans is a highly unusual organism that lacks certain metabolic pathways that occur in virtually every other living thing and get their own phylum in the Archaea domain. Its genome is 490 885 pairs of bases. This is one of the smallest genomes of any living thing. As c. Rudii , n. Equitaans is a compulsory symbiont of another organism, in this case Archeon ignicoccus , from which it acquires many basic biomolecules.

of all above uveThe genomes were the organism bearing the genome of another. But the smallest genome from any organism for wild organism can be found in bacteria mycoplasma genitalium , which is found on the airways and genitalia of primates such as humans. This bacterium was first isolated in 1980 from the urethral samples of two male colors with inflammation of the urethra. He thought he was the first among the smallest genomes under the discovery of c. m. Genitalium was used as a model for a minimum genome project that seeks to create a bacterium with a minimal genome necessary to maintain life.
