a
(a) : The expression of the genetic material occurs normally through the production of proteins. This involves two consecutive steps. These are transcription and translation. The $DNA$ codes for the production of messenger $RNA\ (mRNA)$ during transcription. Messenger $RNA$ carries coded information to ribosomes. The ribosomes read this information and use it for protein synthesis. This process is called translation. $F.H.C.$ Crick described this undirectional flow of information in $1958$ as the ‘central dogma of molecular biology’.
