Which college classes would a student most likely take to become an oceanographer? select 4 choices.

I do not see the four choices, but here are the likelihoods; biology, chemistry, geology, and physics.

This is because there are four main components of study when it comes to becoming an oceanographer:

biological – studying marine plants and animals

physical – exploring water temperature, density, wave motion, tides and currents

geological – examining the structure and make-up of the ocean floor

chemical – analysing the chemicals in sea water and the impact of pollutants

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.'
