b. lithosphere, asthenosphere, mesosphere   is the answer most likely

her next move would be to use agarose gel electrophoresis to separate the dna molecules of varying length and create a dna fingerprint.

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.'

you know they are heterozygous for a trait because they have it as jj or jj.
