Central Dogma

Question 1

RNA Polymerase I

Answer 1

Makes most rRNA genes

Question 2

RNA Polymerase II

Answer 2

reads DNA sequence to make mRNA

Question 3

RNA polymerase III

Answer 3

makes tRNA

Question 4

Where is Bre Found

Answer 4

-35 from start

transcription factor TFIIB

Question 5

Where is TATA found

Answer 5

-30 from start

transcription factor TBP

Question 6

Where is INR

Answer 6

right at transcription point (initiator)

Tanscription factor TFIID

Question 7

Where DPE found

Answer 7

+30 from transcription point

Transcritpiton factor TFIID

Question 8

Amino Acid is attached to ____ end of tRNA

Answer 8

3’

Question 9

First Amino acid binds to what site on rRNA?

Answer 9

Met binds to P site of rRNA which then allows the large rRNA subunit to come in

Question 10

5’ Capping and addition of the poly A tail occurs on the

Answer 10

the pre-mRNA as it is forming the mautre mRNA in the nucleus

Question 11

Introns are normally flanked by which bp’s

Answer 11

5’ - Exon - (GU-Intron- AG)- Exon-3’

Question 12

Introns are removed by?

Answer 12

snRNPs: small nuclear ribonucleoprotein particles

Question 13

HAT

Answer 13

histone acetylating protein: unwinds DNA and allows for easier transcription
HAT binds to activator to unwind

Question 14

HDAC

Answer 14

Histone Deacetylase: removes acetyl group from histone making it bind DNA tighter
HDAC binds to repressor to tightly coil DNA
