which of the following accurately describes fermentation?           a. fermentation can only occur in the presence of oxygen.   b. fermentation generates more atp than cellular respiration.   c. fermentation makes nad+ needed to keep glycolysis going.   d. fermentation always produces carbon dioxide.

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.'
