Definitions/Explanation : Replication fork & Transcription
For long $DNA$ molecules, since the two strands of $DNA$ cannot be separated in its entire length the replication occur within a small opening of the $DNA$ helix referred to as replication fork.
$=$ The process of copying genetic information from one strand of the $DNA$ into $RNA$ is termed a transcription.
At what level gene expression does not occur ?
During in vitro synthesis of $DNA$, a researcher used $2',\,3'$ -dideoxy cytidine triphosphate as raw nucleotide in place of $2'-$ deoxy cytidine. What would be the consequence ?
