Why is it so important to be able to amplify dna fragments when studying genes? dna fragments are too small to use individually. a gene may represent only a millionth of the cell's dna. restriction enzymes cut dna into fragments that are too small. a clone requires multiple copies of each gene per clone?

Option A

Explanation:

It is important that the fragment of DNA should be amplified in order to get an optimum of DNA which is to be used for any purposes. While performing any experiment or using the DNA for research purposes requires DNA in a amount which is easily used for experiment.

A small size of DNA or a fragment of DNA is not suitable for the experiment. Any detection of bacterial growth, et cetera requires DNA in an optimum amount.

So, it should be amplified prior to the experiment.

answer: land bridge theory. land bridge theory held that shifting portions of dry land explained the finding of identical species on different continents. plate tectonic theory eventually eliminated the land bridge theory.

the correct answer is b
