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.

2, 4 , 1 and 3

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

the oxygenated blood then leaves the lungs through pulmonary veins, which return it to the left heart, completing the pulmonary cycle. this blood then enters the left atrium, which pumps it through the mitral valve into the left ventricle. from the left ventricle, the blood passes through the aortic valve to the aorta.

deoxygenated blood leaves through the right ventricle through the pulmonary artery. from the right atrium, the blood is pumped through the tricuspid valve (or right atrioventricular valve), into the right ventricle.

it is either c or d and i know for sure it is not a or b
