While genetic engineering has positive benefits, there are also concerns associated with the
widespread use of genetic engineering in agriculture. If many farmers begin to plant more
genetically modified crops that have an increased tolerance to insects, which of the following
may result?

answer; the tunica intima also called tunica interna, consists of elastic fibers,connective tissue and smooth muscle cells;

meiosis is the correct answer

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.'
