Protein synthesis

Vedclass · Answer

(D) $DNA$ is not directly involved in protein synthesis. $DNA$ acts as a template for the synthesis of $mRNA$ (transcription),$tRNA$,and $rRNA$. $DNA$ also acts as a template for its own replication (synthesis of another $DNA$ strand). However,$DNA$ does not move to the site of protein synthesis (ribosomes) to directly guide the process. Instead,it transfers its genetic information to $mRNA$ molecules,which then move to the ribosomes to direct the synthesis of proteins.
