b) blood typing
c) dna sequencing
d) paternity testing

The right answer is C) DNA sequencing.

DNA sequencing is a technique that revolutionized molecular biology in the 1970s, only about 20 years after the establishment of the DNA structure by Watson and Crick. DNA, the genome contained in each of our cells, contains the information necessary for the expression of genes, information that is important to biologists.
