Protein Synthesis

How are amino acids assembled during translation?
Translation assembles amino acids into a polypeptide chain by reading the mRNA codons and using charged tRNAs as adaptors. Key points and steps:

mRNA attaches to the ribosome.

tRNA molecules transport amino acids to the ribosome.

Anti-codons and codons match up and form complementary base pairs.

Peptide bonds form between adjacent amino acids to form the protein.

Answer 1

All four apply.

- mRNA attaches to the ribosome — the ribosome reads the mRNA codons.
- tRNA molecules transport amino acids to the ribosome — each tRNA carries a specific amino acid.
- Anticodons and codons match up and form complementary base pairs — this ensures the correct amino acid is added.
- Peptide bonds form between adjacent amino acids to form the protein — the ribosome catalyzes peptide bond formation, producing the polypeptide.
