In prokaryotic replication, all DNA polymerases are capable of all of the following tasks except:
A) Reading a template strand and putting the complementary base in the correct position
B) Polymerizing DNA in the 5' to 3' direction
C) Excising DNA in the 3' to 5' direction
D) Excising DNA in the 5' to 3' direction
E) All of these are capabilities of all DNA polymerases

Question

Quizplus · Accepted Answer

DNA polymerases in prokaryotes can read a template strand and synthesize the new strand in the 5' to 3' direction, and they have 3' to 5' exonuclease activity for proofreading, but they do not have the capability to excise DNA in the 5' to 3' direction.
