Being able to amplify specific DNA fragments is critical our ability to study genes because ________.
A) before amplification, DNA fragments are likely to bind to RNA and would no longer be able to be analyzed
B) a gene may represent only a millionth of the cell's DNA
C) restriction enzymes (endonucleases) cut DNA into fragments that are too small
D) making a clone requires multiple copies of each gene per clone

Question

Quizplus · Accepted Answer

A gene may represent only a very small fraction of the cell's total DNA, making it difficult to study without amplification techniques like PCR (Polymerase Chain Reaction) that can selectively amplify the fragment of interest from the entire genome.
