what the function of DNA?

Answer 1

The key to understanding the function of DNA molecule is layered on the pattern of bases along one strand, of the two, that is formed, that is being transcribed into RNA and therefore being translated into a protein. The "readable" strand contains the information (understood as the pattern of base sequences) needed to build a whole protein or group of proteins. So, the recipe for each protein is encoded in a sequence of bases. An analogy is the way letters form written words; but protein is more like a long sentence than a single word, since it may be formed from hundreds of building blocks, called amino acids. The gene is a coded recipe for building a protein. One strand of DNA (called the "sense" strand) contains the recipe for the protein.

Answer 2

Deoxyribonucleic Acid, (DNA), contains the biological and genetic instructions that control the day to day function of cells. It contains the directions necessary to construct other components of cells, such as proteins and RNA (Ribonucleic Acid).
