A researcher needs to clone a sequence of part of a eukaryotic genome in order to express the sequence and to modify the polypeptide product. She would be able to satisfy these requirements by using which of the following vectors?
A) a bacterial plasmid
B) BAC to accommodate the size of the sequence
C) a modified bacteriophage
D) a human chromosome
E) a YAC with appropriate cellular enzymes

Question

Quizplus · Accepted Answer

Yeast Artificial Chromosomes (YACs) are capable of accommodating large sequences of DNA, such as those found in eukaryotic genomes, and can be used in yeast cells to express and modify polypeptide products. They can also be engineered to include necessary cellular enzymes for specific modifications.
