Why do you think carbon has an entire branch of
chemistry devoted to its study?

Carbon has the ability to form 4 bonds with surrounding atoms. It can also form branches, which can be tens of hundreds of carbons long. There are millions of variations of carbon-containing compounds, so a whole branch of chemistry is needed in order to comprehend them.

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.'
