Untie the secret [DNA]


When the gene is found DNA, people still would like to know how this DNA is a kind of things, it is through what specific way to the lives of so many messages to the new successor?

First people would like to know what DNA is composed of human love is always asked at the end of this plane. The results have a called Ryun scientists through research, found that DNA is from four smaller things component, the total of these four things named nucleotides, as the four brothers, they are both named nucleotide, but name is different, namely adenine (A), guanine (G), cytosine (C) and thymine (T), which are difficult to remember names, but as long as the DNA is from four to remember nucleotides only casually together, and their mutual connection there is no law, but later nucleotide in fact not the same, but they are interconnected combination of changing the way great mysteries. Now, the people have to understand the genetic basically how it happened. Studies on the biology of the 20th century discovery: the body from cells, and cells from the cell membrane, cytoplasm and nucleus formed. Known in the nucleus in a substance called chromosomes, some called it mainly by the deoxyribonucleic acid (DNA) of the material.

Of the genetic material found in all cells, this kind of material called RNA. DNA from the nucleotide polymerization. And each nucleotide phosphate, ribose and a base. There are five bases, respectively adenine (A), guanine (G), cytosine (C), thymine (T), and uracil (U). Each contains only the five nucleotide bases in kind.

Single nucleotide linked together into one, two nucleotide chain at a certain order, and then twisted into a "Serratula" sample, a deoxyribonucleic acid (DNA) of the molecular structure. In this structure, each composed of three base pairs can be a genetic "password" and a DNA, as many as several million base pairs, each of the DNA is a genetic code greatly this, the inside of the genetic information countless more of this DNA molecule exists in the nucleus on the chromosomes. They will be split with the transfer of genetic code.

The genetic traits to be passed by password. Probably have 25,000 genes, and each gene is by password to decide. The same gene in both parts have different parts. Different people different from some of its decisions, that is, human diversity. A total of 3 billion DNA genetic code, are composed of about 25,000 genes.
