Transcription

starts at initiator region and ends at stop region.

starts at operator region and ends at telomeric end.

starts at promoter region and ends at terminator region.

starts at $CAAT$ box and ends at $TATA\; box.$

Solution

Formation of $mRNA$ from $DNA$ is called as transcription. The segment of $DNA$ involved in transcriptions is cistron, which have a promoter region where initiation is started and terminator region where transcription ends. Enzyme involved in transcription is $RNA$ polymerase-II.
