Question

Which one of the following is true of tRNAs?

There are four types of tRNA.
Each tRNA binds a particular codon.
tRNAs carry special sequences known as codons.
tRNAs are double-stranded.
All of the listed answers are correct.
None of the listed answers is correct

Answer 1

Each tRNA binds a particular codon on the mRNA during protein synthesis.

Step-by-step explanation:

tRNA (transfer RNA) molecules play a crucial role in protein synthesis. They are structural RNA molecules that bind to sequences on the mRNA template and add the corresponding amino acid to the growing polypeptide chain. Each tRNA carries a specific anticodon that base pairs with a specific codon on the mRNA. Therefore, the correct answer is: Each tRNA binds a particular codon.
