Cerebellum

Explanation:

The cerebellum is a region of the brain whose main function is to integrate the sensory and motor pathways. There is a large number of nerve bundles that connect the cerebellum with other brain structures and with the spinal cord. The cerebellum integrates all the information received to specify and control the orders that the cerebral cortex sends to the musculoskeletal system through the motor pathways. It is the regulator of physiological tremor.

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.'
