Which of the following peptide address label target the proteins to chloroplasts?
EXPLANATION
Translation, Protein Sorting/Targeting & Gene
- Chloroplast Transit Peptide (cTP): An N-terminal peptide extension (typically 30–100 amino acids enriched in serine and threonine, lacking acidic residues) that directs newly synthesized nuclear-encoded proteins through the TOC/TIC translocon machinery into the chloroplast stroma.
- Other Address Labels:
- Presequence: Targets proteins to the mitochondrial matrix.
- Signal Peptide: Targets nascent polypeptides to the endoplasmic reticulum lumen. (Correct answer: Option 1)
