Which Type of Vector Can Replicate in Both E

Question

Which type of vector can replicate in both E.coli and another species?
A) Plasmids
B) Lambda phage
C) Cosmids
D) Shuttle vectors
E) None of these

Accepted Answer

Shuttle vectors are designed to replicate in two or more hosts, allowing for the easy transfer of genetic material between different species. Therefore, shuttle vectors can replicate in E.coli and another species, making them the best choice for this question. Plasmids can only replicate in one species, while lambda phage and cosmids have limitations in their ability to replicate in both E.coli and other species.
