A mutation may be harmful to an organism if it... A. Improves the DNA of the organism
B. Changes the genotype of the organism
C. Reduces the organisms's chances for survival and reproduction.
D. Change the phenotype of the organism

The answer is C. Reduces the organisms's chances for survival and reproduction.

C

Explanation:

A. If it improved it's not harmful

B. That is what a mutation is

C. They need to survive, so if it reduces their chances to do so it's bad.

D. That doesn't matter most of the time

ans.

dna fingerprinting is defined as a process that determines the dna characteristics of an individual. these dna characteristics are unique among individuals as their fingerprints, so it is known as dna fingerprinting.

steps of dna fingerprinting includes extraction of dna from sample, amplification of dna, restriction digestion of amplified dna, and then analysis of dna by gel electrophoresis, respectively.

thus, the next step performed by the scientist is 'to cut the amplified dna (obtained by polymerase chain reaction) by restriction enzymes that cleave the dna into fragments and their analysis.'
