Scientists apply the concept of a molecular clock to estimate the time to species evolved separately. Which data are most useful for the estimation?
A. Common traits of the two species
B. Homologies among the two species
C. DNA sequence differences between the two species
D. DNA fingerprinting of common fossils

DNA sequence differences between the two species is the most useful data used by the scientist for the estimation of the molecular clock.

Explanation:

ya the other dude is right

ans.

dna fingerprinting is defined as a process that determines the dna characteristics of an individual. these dna characteristics are unique among individuals as their fingerprints, so it is known as dna fingerprinting.

steps of dna fingerprinting includes extraction of dna from sample, amplification of dna, restriction digestion of amplified dna, and then analysis of dna by gel electrophoresis, respectively.

thus, the next step performed by the scientist is 'to cut the amplified dna (obtained by polymerase chain reaction) by restriction enzymes that cleave the dna into fragments and their analysis.'
