What is DNA?

DNA (desoxy ribo nucleic acid) in living things basic inheritance agent. Giant molecule. (Height 1-1.5m. Long.) Chain-shaped. There is a feature of double-helix. Similar rope ladder. The long sides of the rope ladder made up of sugar and phosphate molecules. This is the "long" rope wrapped and protected manner in the cell core. (Pitted cells in the cytoplasm.) Consists of the addition of various simple molecules to each other. There are four different types of ring. (These are called nucleoid.) Names adenilik acid, guanylic acid, sitidilik acid and timidilik acid. Abbreviations A, G, C and T. Information stored in the DNA of an organism's heredity. In other words, all of an organism transferred to the next generations "knowledge" is through DNA. Transfer any means inherit a property, means a piece of DNA transfer. Genes DNA. Information is DNA. DNA information. If we think of the genetic information contained in DNA as a book, this book is for all the letters, words, sentences and paragraphs is possible to say that together form a long chain. Defined so that all departments and functions of living things. If you have an identical twin of this organism, it also contains the same DNA. In the same book, one more: What is the difference in a letter nor a word. Books of various genres, a lot of inside story tells quite a different, albeit similar sentences. This is a long chain (in the book), a difference that might occur, when the next generation, with a book written in a different population of "other life" is faced with.
What is the duty and importance of DNA?
DNA molecule that is part of each 'gene' is a particular feature of the human body. The animal's body shape, it's the business part of the body and organs function, the genetic codes of the proteins to be produced in the cell, the amount of proteins produced in the controls (gene regulation) in the DNA of what it takes to maintain its life as planned, coded.
DNA in the cell location
Consists of about 3 billion base pairs of DNA in human cells and about 1 meter in length. This one-meter-long polymer, our eyes can not see, even stored in the cell nucleus so small. 'Histone' where tiny proteins known as elsewhere in the DNA chromosomes by wrapping packaged does not stop, the necessary enzymes gene regions codes off using mRNA (messenger ribonucleic acid) molecules other by means of a so-called replicas removed, by means of this copy is synthesized proteins. After you have read the required region of DNA chain in this way turns again into the old packed. But maybe not think about it at the same time opened dozens of different regions of DNA, gene passwords, read and closed again. Think of a ball of yarn, this middle of the balls, at the same time you want to open a place to the end of the beginning, and then is wound still intact orderliness is this possible? That seemingly impossible event every moment, in every cell of every living thing faultless, flawless, perfectly even inanimate atoms, molecules yaptırılıyor hands
