Codons are three-base sequences that specify the addition of a single amino acid. How do eukaryotic codons and prokaryotic codons compare?
A) Prokaryotic codons usually contain different bases than those of eukaryotes.
B) Prokaryotic codons usually specify different amino acids than those of eukaryotes.
C) The translation of codons is mediated by tRNAs in eukaryotes, but translation requires no intermediate molecules such as tRNAs in prokaryotes.
D) Codons are a nearly universal language among all organisms.

Quizplus · Accepted Answer

Codons are a nearly universal language among all organisms, meaning they are generally shared across both eukaryotic and prokaryotic organisms. While there are some minor variations in codon usage between these groups, the fundamental genetic code is largely the same. Therefore, choices A, B, and C are incorrect.
