Question

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

Answer 1

Answer: C. the sequence of nucleotides in DNA

Explanation: Our genotypes and eventual phenotypes are derived from the way our DNA is scripted. The only thing that determines this is the specific ordering and sequence of the A, T, C and G nucleotides that get coded into mRNA and into proteins that form our phenotype. Hope this helps!
