How does energy acquisition in the deep sea differ from energy acquisition near the ocean’s surface?

a.
organisms in the deep sea acquire energy directly from the sun.
b.
organisms near the ocean’s surface rely on chemosynthesis rather than photosynthesis.
c.
organisms in the deep sea do not have direct access to sunlight.
d.
organisms in the deep sea have no means to obtain energy unless they travel to the ocean’s surface.

the dna molecules have a negative charge because of the phosphate groups in their sugar-phosphate backbone, so they start moving through the matrix of the gel towards the positive pole. power is turned on and dna fragments migrate through gel (towards the positive electrode).

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.'
