Question

24 question (1 point) 1st attempt which proteins bind to nuclear localization signals on newly synthesized proteins? choose one: nuclear pore proteins nuclear import receptors cytosolic fibrils nuclear export receptors signal - recognition particles (srps)

Explanation:

Nuclear import receptors recognize and bind to nuclear localization signals on newly - synthesized proteins to facilitate their transport into the nucleus. Nuclear pore proteins form the structure of the nuclear pore but do not directly bind to these signals. Cytosolic fibrils are part of the nuclear pore complex structure and not the binding proteins for nuclear localization signals. Nuclear export receptors are involved in transporting proteins out of the nucleus. Signal - recognition particles are involved in the targeting of proteins to the endoplasmic reticulum, not nuclear import.

Answer:

B. nuclear import receptors
