Summary Introduction
Introduction: DNA consists of genetic instructions in the form of gene sequences. It directs messenger RNA (mRNA) synthesis in the cell. During the formation of mRNA in a process known as transcription, each letter in the gene sequence is copied which codes for a particular amino acid. The polypeptide chain is synthesized on the basis of amino acid sequences in the reading frame. This process is known as translation.
