Question

Quizplus · Accepted Answer

Since the turkey phenylalanine hydroxylase shares its function with other birds, the closest match is likely to be chicken. The other options, which include fish, primates, and insects, are less likely to have a similar sequence due to evolutionary distance and functional differences in metabolism.
