A population of snakes includes solid-colored snakes and banded (striped) snakes. On the mainland, the snakes are mostly solid. On a nearby island, the snakes are mostly banded. You hypothesize that the reason for this observation is that the environments on the mainland and island are different, and banded snakes are favored in the island environment. Which of the answer choices are possible alternative hypotheses to explain why the snakes on the island are mostly banded? Select all that apply.

cell division is not regulated in tumor cells.

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.'
