Question 1

Label the transcribed gene in the direction synthesized by RNA polymerase

Answer 1

promoter, methyl cap, 5’ end, initiation, stop, 3’ end, terminator, poly a tail

Question 2

What is a holoenzyme?

Answer 2

sigma plus the subunits, needed for initiation but falls off at elongation

Question 3

Does RNA polymerase need a primer?

Answer 3

no

Question 4

What is RHO dependent transcription?

Answer 4

inverted complementary sequence plus the RHO enzyme, the RHO enzyme will catch up to the loop and break

Question 5

What is intrinsic transcription?

Answer 5

Inverted complementary sequence + string of a sequence, hairpin loop forms and physically dissociated RNA polymerase

Question 6

What causes overlapping genes?

Answer 6

transcription and translation occurring at the same time

Question 7

What do enhancers and silencers do?

Answer 7

enhancers increase transcription, silencers decrease transcription
