Answer

Why is it so important to be able to amplify DNA fragments when studying genes

A) Before amplification, DNA fragments are likely to bind to RNA and 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) A clone requires multiple copies of each gene per clone.
