Question

What is the correct order for the following events in excision repair of DNA? (1) DNA polymerase I adds correct bases by 5¢ to 3¢ replication. (2) Damaged bases are recognized. (3) DNA ligase seals the new strand to existing DNA. (4) Part of a single strand is excised.

Answer 1

2, 4 , 1 and 3

Step-by-step explanation:

The correct order for events in excision repair of DNA are:-

2, 4 , 1 and 3 thatv is the

1st step would be:

(2) Damaged bases are recognized.

2nd step of the process

(4) Part of a single strand is excised.

3rd step will be

(1) DNA polymerase I adds correct bases by 5¢ to 3¢ replication.

and the final step in excision repair of DNA is

(3) DNA ligase seals the new strand to existing DNA
