Question:
The major advantage of using artificial chromosomes such as
YACs and BACs for cloning genes is that
A) plasmids are unable to replicate in cells.
B) only one copy of a plasmid can be present in any given
cell, whereas many copies of a YAC or BAC can coexist in a single cell.
C) YACs and BACs can carry much larger DNA fragments than
ordinary plasmids can.
D) YACs and BACs can be used to express proteins encoded by
inserted genes, but plasmids cannot.
E) all of the above
Answer:
C) YACs and BACs can carry much larger DNA fragments than ordinary plasmids can.
