Question

question 10 of 10
what are the two functional parts of a charged trna?
a. a start codon and a stop codon
b. an amino acid and an anticodon
c. a prokaryote and a eukaryote
d. two different nucleic acids

Explanation:

A charged tRNA (transfer RNA) has two main functional parts. The amino acid is attached to one end of the tRNA. This amino acid is what will be added to the growing polypeptide chain during translation. The anticodon is a sequence of three nucleotides at the other end of the tRNA. It pairs with the complementary codon on the mRNA (messenger RNA) to ensure the correct amino acid is added in the right position.

• Option A: Start and stop codons are on mRNA, not part of tRNA's functional parts.
• Option C: Prokaryote and eukaryote are types of organisms, not related to tRNA structure.
• Option D: tRNA is a single type of nucleic acid (RNA), not two different nucleic acids.

Answer:

B. An amino acid and an anticodon
