Chapter 17 RNA Processing, Transcription, Translation

Question 1

sigma

Answer 1

sigma must bind to the RNA polymerase before transcription can begin, forces the RNA polymerase to bind to the specific promotor sites on DNA by guiding them there, binds to the -35 to -10 box area on DNA strand

Question 2

holoenzyme

Answer 2

holoenzyme is a molecule made up of sigma bound to RNA polymerase, contains RNA as a core enzyme

Question 3

core enzyme

Answer 3

the enzyme in a molecule that contain the active sitefor catalysis

Question 4

elongation

Answer 4

the phase of transcription when RNA polymerase is moving along DNA template strand

Question 5

DNA coding strand

Answer 5

the sequence of base pair that the mRNA will be copying (by adding complementary bases to the opposite strand)

Question 6

termination

Answer 6

ends transcription, occurs when the RNA codes for a termination signal that cause the RNA to form a hair pin, which disrupts the interaction between polymerase and transcript

Question 7

RNA polymerase

Answer 7

3 types, each produces a different type of RNA
