문제 76a
A base substitution changes a codon for an enzyme from GCC to GCA. Why is there no change in the amino acid order in the protein?
문제 76b
In sickle-cell anemia, a base substitution in the hemoglobin gene replaces glutamate (a polar amino acid) with valine. Why does the replacement of one amino acid cause such a drastic change in biological function?
문제 77a
A base substitution for an enzyme replaces leucine (a nonpolar amino acid) with alanine. Why does this change in amino acids have little effect on the biological activity of the enzyme?
