ATP, RNA, and DNA
Garrod hypothesized that "inborn errors of metabolism" such as alkaptonuria occur because
Genes dictate the production of specific enzymes, and affected individuals have genetic defects that cause them to lack certain enzymes.
Which of the following nucleotide triplets best represents a codon?

A simple metabolic pathway is shown below. A mutation results in a defective enzyme A. Which of the following would be a consequence of that mutation? A simple metabolic pathway is shown below. A mutation results in a defective enzyme A. Which of the following would be a consequence of that mutation?
An accumulation of A and no production of B and C
