None of the above
Explanation: 

Detailed explanation-1: -2. How has DNA sequencing affected the science of classifying organisms? DNA sequencing has allowed scientists to be able to determine how certain animals and plants are genetically related. This is important because species are not being related to each other just by physical traits, but also their genetic makeup.

Detailed explanation-2: -The sequences of genes or proteins can be compared among species and used to build phylogenetic trees. Closely related species typically have few sequence differences, while less related species tend to have more.
