Winds are generated by pressure differences in the atmosphere. which factor is directly responsible for these pressure differences in the atmosphere? a) the day–night cycle on earth b) uneven landforms on earth's surface c) rotational motion of earth about its own axis d) uneven heating of earth's atmosphere by the sun

what is the statement?

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.'
