Question 6

Promoter

Answer 6

DNA sequence which the transcription unit recognizes and binds to

Question 7

RNA-coding region

Answer 7

Region of DNA that is copied into an RNA molecule

Question 8

Terminator

Answer 8

Sequence of DNA that signals where transcription ends

Question 9

RNA is synthesized by _____

Answer 9

ribonucleoside triphosphates

Question 10

Omega RNA Polymerase Function

Answer 10

Stabilizes core structure

Question 11

Sigma RNA Polymerase Function

Answer 11

Regulates binding to the promoter and initiation

Question 12

Consensus Sequence

Answer 12

Sequence of DNA nucleotides common in most prokaryotes

Question 13

Consensus sequences are located where?

Answer 13

35 and 10 bp upstream of transcription start sites

Question 14

RNA Polymerase during elongation does?

Answer 14

Unwinds DNA at front edge of transcription bubble, synthesizes RNA, proofreads

Question 15

Rho dependent termination

Answer 15

RNA polymerase pauses at terminator, rho catches up and ends transcription

Question 16

Rho independent termination

Answer 16

Hairpin loop formed, string of Uracils formed that displaces RNA
