Chapter 23, Problem 10EQ
Summary Introduction
To review:
The molecular feature of the BAC (bacterial artificial chromosome) vector and its advantages over a plasmid or viral vector.
Introduction:
The physical mapping of the relative locations of genes requires the development of cloning vectors that store information about genes in the library. These vectors are madeusing viruses, plasmids, or artificial chromosomes.
