Which of the fallowing describes the difference between nitrogen-14 and nitrogen-15

Nitrogen-14 has 14 protons and neutrons, where nitrogen-15 has 15 protons and neutrons. Nitrogen-14 has a mass number of 14. Nitrogen-15 has a mass number of 15.

I hope this was helpful.

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.'
