Bacterial Cell Cycle

Front 1

True or False: Translation occurs after transcription in bacteria

Back 1

False. Transcription and translation occur simultaneously in a bacterial cell

Front 2

True or False: In bacteria, RNA polymerase requires a primer

Back 2

False. RNA polymerase doesn't require a primer and can start a chain de novo

Front 3

Where is the -10 Pribnow box found?

Back 3

in the bacterial promoter, which serves as the binding site for RNA polymerase

Front 4

True or False: Transcription can occur without the promoter

Back 4

False. RNA polymerase cannot bind without a promoter

Front 5

the sigma factor is needed for which part of transcription?

Back 5

initiation

Front 6

which DNA strand is not transcribed?

Back 6

the coding strand

Front 7

what is the most common type of termination?

Back 7

rho dependent rho protein

Front 8

what are two types of rho independent termination?

Back 8

a series of U's or inverted repeats that make stem-loop structures

Front 9

Name 4 inhibitors of transcription

Back 9

Rifampin, Streptovaricin, Streptolydigin, and Actinomycin D

Front 10

What does it mean for the genetic code to be degenerate?

Back 10

each amino acid has more than one code

Front 11

What is the initiating amino acid in bacteria?

Back 11

N-formylmethionine

Front 12

What inhibits peptidyl transferase?

Back 12

Chloramphenicol

Front 13

What is the Shine-Dalgarno sequence?

Back 13

5' AGGAGGU 3'

Front 14

What is the function of the Shine-Dalgarno sequence?

Back 14

it immediately proceeds the AUG start codon and positions it so that it binds anterior to an initiator tRNA anticodon
