Protein Synthesis · Botany

During protein folding, 'Chaperone' proteins help by:

  1. Degrading proteins that are already terminally misfolded
  2. Preventing improper folding and aggregation of proteins
  3. Synthesizing new mRNA strands during gene transcription
  4. Transporting tRNA molecules to the ribosome site
Show answer and explanation

Correct answer: Preventing improper folding and aggregation of proteins

Chaperones bind to partially folded or unfolded polypeptide chains. They ensure that the protein reaches its correct 3D conformation, which is essential for its biological activity.
