Ascientist wants to make a dna fingerprint and she used polymerase chain reaction. what should be her next move

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.'

hello there,

igneous rock formed from below the surface would have more crystals because

answer: because magma cools more slowly than lava

the supermassive black hole is in the middle of the galaxy.
