1. Why is the inside of the digestive system not really "inside” your body?

The digestive system is really just a tube that begins at your mouth and ends at the rectum. Most of it is filled with bacteria compared to the other parts of your body which are usually sterile with no bacteria.

Explanation:

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.'
