DNA function

DNA serves convey genetic information from parent to the next generation and regulate the development of the body's metabolism. Thus, it can be said that DNA is the gene itself. DNA can also oversee the activities of the cell by ordering the establishment of all kinds of proteins (enzymes) in the cell. DNA in the nucleus of cells and the formation of a protein generally occurs on ribosomes, which is in the cytoplasm. Thus, the information in DNA to be translated first by a particular compound and carried by the compound from the nucleus to the cytoplasm. DNA will form other compounds in conveying genetic information that will instruct the synthesis of proteins. The compounds formed by DNA, the messenger RNA, transfer RNA and ribosomal RNA.


DNA function

Function compounds formed by DNA
1) RNA-d

RNA-d duty convey genetic information from DNA in the form of genetic code from the nucleus to the ribosomes in the cytoplasm. Genetic code N in the form of base sequences called codons. RNA-DNA formed by d if necessary alone. When it is completed the task, RNA-d will be destroyed in the plasma. Molecules of RNA-RNA d is the longest in the cell.

2) RNA-t

T made ​​by RNA-DNA in the cell nucleus, but it is always present in the cytoplasm and very small molecular size. RNA-t function is to transport amino acids to the ribosome in accordance with the codes contained in the RNA-d. Each amino acid requires a special t-RNA. In RNA-t, there are two important parts, namely the anticodon (base sequences N) associated with the codons and the amino acids that bind to the other.

3) RNA-r

RNA-r serves as an engine builder that moves in one direction along the RNA-d. RNA-r created by a specific gene in the DNA of chromatin attached to the nucleolus. RNA-r even if not used always present in the ribosome.
