Deoxyribonucleic acid, or DNA, is a nucleic acid that contains the genetic instructions used in the development and functioning of all known living organisms (with the exception of RNA viruses). The main role of DNA molecules is the long-term storage of information. DNA is often compared to a set of blueprints, like a recipe or a code, since it 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.
Functions of DNA
The function of DNA is critical to the succession, and life on the genetic blueprint encoded protein. Because the function of DNA in the human body growth and maintenance responsibility and difficulty of life, it is not surprising that the discovery of DNA led to the development in the treatment of this disease appeared in large numbers. DNA of an organism contains the instructions of the development and reproduction - the end, its survival.
Coding for Proteins
DNA preservation of the protein, which is in our body, includes a lot of work to do complex molecules of the code. The information in the original DNA is 'read', and then it is transcribed into messenger molecules. After the messenger molecule, held in this information into 'language', the body can understand. This language is amino acids, proteins also known as one of the cornerstones. It is this specific language, how it provides a specific amino acid to be produced proteins. If you are twenty different amino acids like, you can see, ordering can produce a wide variety of proteins. (Russell & Peter, 2001)
DNA Replication
DNA replication is critical to almost endless list of functions, from maintenance and reproduction ...
