You are using genetic engineering to design a protein that needs to be synthesized in the cytoplasm and then localized in the nucleus of the cell.To accomplish this,you could add
A)a DNA sequence for a nuclear localization signal into the DNA that will be present in the mature protein.
B)the protein during mitosis,at a time when the nuclear membrane is dispersed.
C)a nucleotide or few nucleotides to the DNA sequence for the protein.
D)a series of specific polysaccharides to the carboxyterminal end of the protein.
E)inverted repeats to the DNA sequence for the protein.

Question

Quizplus · Accepted Answer

A nuclear localization signal (NLS) is a sequence of amino acids in a protein that acts as a 'tag' to direct the protein to the nucleus. Adding a DNA sequence that codes for an NLS to the gene for the protein ensures that, once synthesized in the cytoplasm, the protein will be transported into the nucleus.
