1. What is the end result of using the technique known as polymerase chain reaction (PCR) on a DNA fragment?
A. A pattern of gene fragments separated by size
B. The sequence of the entire genome of an organism
C. Many copies of a DNA fragment
D. A single, large protein molecule

the types of mutations include: missense mutation: this type of mutation is a change in one dna base pair that results in the substitution of one amino acid for another in the protein made by a gene. nonsense mutation: a nonsense mutation is also a change in one dna base pair.

explanation:

what have scientists found to be the most efficient and effective way to insert new sequences into an individual? a-scientists have created genetically altered foods that release dna during digestion. b-scientists use viruses to insert specific gene sequences. c-scientists irradiate genes so that they can be absorbed through the skin.
