Question

Arrange the following proteins involved in replication of DNA in order of action from first to last. (Order them from 1-6, with 1 being the first)

Primase
Helicase
DNA polymerase III
ss-DNA binding proteins
DNA polymerase I
DNA ligase

Answer 1

proteins involved in replication of DNA in order of action from first to last is:

1.Helicase- helps in unwinding of the double stranded DNA

2. SS-DNA binding proteins - Prevents the single strands of the DNA to get bound again to form a helix

3. PRIMASE initiates the DNA replication by catalyzing the synthesis of short DNA stretch complementary to the template DNA

4. DNA Polymerase III ia responsible for elongation of DNA during replication by adding nucleotides at the 3' end in the newly formed strand.

5. DNA polymerase I has exonuclease activity ans heloa in proofreading

6. DNA ligase joins the okajaki fragments in the lagging strand
