The DNA is the genetic molecule of a cell in an organism that contains the genetic information stored in forms of genes. The genes are expressed by means of protein synthesis. The genes are formed of particular sequence of nitrogen bases that is called as codon. These codons are transcribed into particular amino acids. This process involves the participation of DNA dependent RNA synthase that produces the mRNA from the portion of DNA by means of transcription. The mRNA that is produced from the DNA is formed of complementary nitrogen bases from the DNA, just exception is that in RNA, thymine is replaced by Uracil. This process is known ad transcription.
