Question

question 8 of 10
how do two alleles for the same gene differ?
a. they use different rules for nitrogenous base pairing.
b. they are made of different types of proteins.
c. they are located at slightly different points on a chromosome.
d. they contain slightly different codes for amino acids.

Explanation:

:
D. They contain slightly different codes for amino acids.

Alleles are variants of a gene. They have different DNA sequences which lead to different codes for amino - acids during protein synthesis. Nitrogenous base - pairing rules are universal (A - T, G - C in DNA), alleles are segments of DNA not proteins, and alleles for the same gene are located at the same locus on homologous chromosomes.
