Prokaryotic Transcription Elongation and Termination

This video presents the same text shown beside it, spoken and on screen. It adds nothing the text does not say.

State

Prokaryotic RNA polymerase elongates an RNA strand in the 5'-to-3' direction until it reaches a terminator sequence, signaling transcription to stop.

Show

RNA polymerase reads the DNA template and builds a complementary RNA strand until a terminator sequence causes it to release.

Watch for

Termination in prokaryotes releases a finished RNA directly — prokaryotic RNA generally needs none of the extensive processing eukaryotic RNA requires.
