Codons Are Three-Base Sequences in MRNA That Specify the Addition

question 10

Multiple Choice

Codons are three-base sequences in mRNA that specify the addition of a single amino acid to the growing protein chain during translation. 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.

Postcentral Gyrus

The region of the cerebral cortex located immediately posterior to the central sulcus, primarily responsible for processing somatosensory information.

Cerebral Palsy

A group of permanent movement disorders that appear in early childhood, often due to brain damage before, during, or shortly after birth.

Premotor Cortex
