The function of tRNA (transfer RNA) molecules is: b. tRNA molecules bring amino acids for the ribosome to link together.
Explanation:
- tRNA molecules play a crucial role in protein synthesis by transferring specific amino acids to the ribosome during the process of translation. Each tRNA molecule carries a specific amino acid and has an anticodon sequence that matches a complementary codon sequence on the mRNA (messenger RNA).
- As the ribosome moves along the mRNA strand during translation, tRNA molecules bring the appropriate amino acids to the ribosome based on the mRNA codons, facilitating the assembly of a polypeptide chain according to the genetic code.
