Question

by 2020, however, there will be a significant change that will make dna fingerprinting obsolete. the handful of markers used in dna fingerprinting will give way to the infinitely more sophisticated personalized dna sequences. fingerprints may give us a match, but dna may tell us what the person

for example, by examining a single cell from a persons dandruff, it is in principle possible (using the polymerase chain reaction process) to reconstruct the entire genome of an individual. possessing the personalized dna

choose the best summary of these two passages.

dna sequencing will replace fingerprinting because it will give scientists more detailed and useful information about people.

dna sequencing will improve fingerprinting technologies because it will provide specific information linked to fingerprints.

dna sequencing will bring significant changes to human genomes because it will cause people to rely on fingerprinting.

Explanation:

The first passage states that DNA fingerprinting markers will be replaced by more sophisticated personalized DNA sequences. The second passage gives an example of how DNA sequencing (using polymerase chain reaction) can reconstruct an entire genome from a single cell. The first option accurately summarizes that DNA sequencing will replace fingerprinting as it provides more detailed and useful information. The second option is incorrect as the text says DNA sequencing will replace not improve fingerprinting. The third option is wrong as it claims DNA sequencing will cause reliance on fingerprinting which contradicts the text.

Answer:

DNA sequencing will replace fingerprinting because it will give scientists more detailed and useful information about people.
