Question

All the information required to target a precursor protein from the cytosol to the mitochondrial matrix is contained within its:N-terminal-targeting sequence.C-terminal-targeting sequence.nuclear localization signal.cytosolic export signal.None of the answers is correct.

Answer 1

N-terminal matrix-targeting sequence.

Step-by-step explanation:

Unfolded proteins enter the mitochondrial matrix with a chaperone protein; the information required to target the precursor protein from the cytosol to the mitochondrial matrix is contained within its N-terminal matrix-targeting sequence.
