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?

The correct answer is: a gene may represent only a millionth of the cell's DNA.
The method used to amplify DNA fragments is called polymerase chain reaction (PCR). PCR is a technique used in molecular biology to produce thousands to millions of copies of a single targeted DNA sequence. When studying a specific gene, the scientist needs to be able to target and focus only on the DNA sequence which constitutes this exact gene. However, a gene is only a very small portion of an organism's genome. Therefore, the scientist uses PCR to amplify this DNA sequence and produce a large number of copies.

idk but if i had to take an educated guess i’d say a c d

Ithink you should go back and learn in school rather then here asking questions
