Answer
DNA is a double helical structure with adenine, guanine, cytosine and thymine base. It contains the code for the sequence of amino acids in proteins. When a cell synthesizes a protein, the base sequence of the gene which codes for that protein is transferred to mRNA. The mRNA is the primary product of the transcription then moves to a ribosome, where the amino acids are linked in the correct sequence to synthesize the protein. Hence the central dogma of molecular biology is the flow of genetic material from DNA to RNA to protein.
DNA====> RNA =====> PROTEIN
