Most of Today's Bacteriophage Cloning Vectors are Derived from Which

Question

Most of today's bacteriophage cloning vectors are derived from which phage?
A) SV40
B) T4
C) Lambda
D) T2
E) pGLO

Accepted Answer

Lambda phage is the most commonly used bacteriophage for cloning vectors due to its large genome size, which allows for insertion of large DNA fragments, and its ability to integrate its DNA into the host genome. Lambda-based vectors can also be easily modified to allow for expression of foreign proteins under specific conditions.
