The purpose of mechanical shearing when generating a genomic library is to
A) generate artificial DNA.
B) get DNA in fragments of the appropriate size.
C) convert mRNA to DNA.
D) generate multiple identical copies of a DNA fragment.
E) decrease the stability of mRNA.

Question

Quizplus · Accepted Answer

Mechanical shearing involves physically cutting DNA into smaller pieces, which allows for the generation of fragments that are of the appropriate size for cloning into a genomic library. This process does not involve the creation of artificial DNA, conversion of mRNA to DNA, or the generation of multiple identical copies of a DNA fragment. It also does not affect the stability of mRNA.
