What is the role of the nuclear localization sequence in a nuclear protein? select one: a. it is bound by cytoplasmic proteins that direct the nuclear protein to the nuclear pore. b. it is a hydrophobic sequence that enables the protein to enter the nuclear membranes. c. it aids in protein unfolding so that the protein can thread through nuclear pores. d. it prevents the protein from diffusing out of the nucleus through nuclear pores?
