Structure

Generally, the closest to the cell B configuration of DNA double helix conformation, it is very similar to model. DNA and RNA molecule - the double helix area and the formation of transcription DNA molecule hybridization RNA conformation close -. Z - DNA to nucleotide dimers for unit, the Lord left to wound is serrated (Z) chain, the name. This configuration for a nucleotide chain of purine cytosine alternate area. In 1989, the American scientists scanning tunneling microscopy method directly observed double-helix DNA double-helix DNA in 1952, Austria, African American biochemist captains E.c hargaff gadamer check (1905 -), the four determination of DNA base, the content of fat poison and found adenocarcinoma of the number of thymine bases, bird whisper fat with equal the number of cytosine. This makes Watson and crick immediately thought of four bases exist between two corresponding relationship, formed the glands and thymine * matching belt whisper, birds and cytosine matching belt whisper.

Unlock the secrets of DNA.

When you find that the correlation between genes and DNA, people still want to know how the DNA of a thing, it is through the life of any specific measures of so much information to the new replacement?First people wanting to know what is composed of DNA, human being dug this love always. Levin is A result of scientists through research, the discovery of DNA consists of four more small things, the four things always name nucleotide, like four brothers, they are surname, but the name but nucleotide, were different adenine (A) and guanine (G), cytosine (C) and thymine bases (T) and the four name written, but just remember to DNA consists of four nucleotide just get together, and their mutual connections without any rule, but later nucleotide, and their mutual combinations of the great mystery.

DNA characteristics

A: the DNA consists of deoxidizing nucleotides of polymerization monomer polymers.B: the DNA of deoxidizing every single nucleotide called a deoxidization nucleotide is composed of three parts: a molecule contain nitrogen base + a molecular five carbon (a) deoxyribose molecular phosphate, and DNA consists of C, H and O N, P, consisting of five elements.C: the DNA containing nitrogen base can be divided into four categories: Guanine (Guanine Thymine (), thiamine (Adenine), Adenine, Cytosine) (Cytosine)D: the DNA of four nitrogen-bearing bases with species. Four bases that contain nitrogen in the proportion between individuals with different species are consistent, but in different between species have differences.E: the DNA of four nitrogen-bearing bases with strange regularity, the proportion of each in an organism's DNA in A (adenine deoxidization nucleotide) = T (thiamine (nucleotide) C (cytosine deoxidization nucleotide) = G (guanine deoxidization nucleotide). A and T between two hydrogen, C in between three and G. Hydrogen

DNA

Deoxyribonucleic acid, or DNA, is a nucleic acid molecule that contains the genetic instructions used in the development and functioning of all known living organisms. The main role of DNA is the lon-term storage of information and it is often compared to a set of blueprints, since DNA contains the instructions needed to construct other components of cells, such as proteins and RNA molecules. The DNA segments that carry this genetic information are called genes, but other DNA sequences have structural purposes, or are involved in regulating the use of this genetic information
