Flashcards in Different DNA and RNA polymerases Deck (12):
1
DNA III polymerase
prokaryotes
Leading and lagging strands
Has 5'-->3' synthesis and
3'-->5"exonuclease activity
2
DNA I polymerase
Prokaryotes
Excises RNA primer
-5' --> 3' exonuclease activity along with 5'-->3' DNA synthesis and proof reading 3'--> 5'
3
DNA polymerase alpha
Eukaryotes
RNA primer and builds okazaki fragments on lagging strand
4
DNA polymerase beta
Eukaryotes
DNA repair
5
DNA polymerase Gamma
Eukaryote
LEADING STRAND
6
DNA polymerase gamma
mitochondrial DNA
7
RNA polymerase I
rRNA
is synthesized in nucleolus
8
RNA polymerase II
mRNA
9
RNA Polymerase III
tRNA
10
alpha- amanitin
Found in Amanita Phalloides (death cap mushrooms) and it inhibits RNA polymerase II. Can cause severe hepatotoxicity if ingested
11
Rifampin
inhibits RNA polymerase in prokaryotes
(recall that prokaryotes have only one type of RNA polymerase and it is a multisubunit complex that makes all 3 kinds of RNA)
