Question

Replication requires DNA Polymerase III

DNA polymerase III holoenzyme: 900 kDa complex
a) a catalytic core ___ subunit
b) a dimerization component ___ that links two cores
c) a processivity component ___ that keeps polymerase on DNA
d) a clamp loader __ that places the processivity subunit on DNA

Answer 1

DNA polymerase III is a 900 kDa complex consisting of different subunits that are involved in DNA replication and synthesis in prokaryotes.

Step-by-step explanation:

The replication process requires DNA polymerase III, which is a 900 kDa complex consisting of several subunits. These subunits are:

1. a catalytic core subunit
2. a dimerization component that links two cores
3. a processivity component that keeps the polymerase on the DNA
4. a clamp loader that places the processivity subunit on DNA

DNA polymerase III is involved in DNA replication and adds deoxyribonucleotides to the growing DNA chain. It is the main enzyme responsible for DNA synthesis in prokaryotes.
