Apaleontologist has recovered a bit of tissue from the 400-year-old preserved skin of an extinct dodo (a bird). to compare a specific region of the dna from the sample with dna from living birds, which of the following would be most useful for increasing the amount of dodo dna available for testing?

Polymerase chain reaction.

Explanation:

The polymerase chain reaction can be defined as the technique which is used to amplify the amount of DNA that is available.

The DNA in small quantity is amplified in order to increase the amount so that the optimum amount of DNA is made available for testing.

For testing the sample of DNA, there must be an adequate amount of DNA  which can be tested. This is reason why PCR must be performed to amplify the amount.

Here also, the amount of the dodo DNA will be amplified by the process of PCR for testing purpose.

i would go with b

cytokinesis occurs after telophase so that eliminates d

and the entire reason for cytokinesis is for cellular reproduction
