Differences in traits such as hair texture are determined by differences in - a) the location of sugar groups in dna. b) the sequence of nucleotides in dna. c) the number of nitrogenous bases in dna. d) the molecules attached to the phosphate in dna.

Differences in traits such as hair texture are determined by differences in the sequence of nucleotides in DNA (Option B).

In conclusion, differences in traits such as hair texture are determined by differences in the sequence of nucleotides in DNA (Option B).

Differences in traits such as hair textures are simply mutation

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.'
