Discover the types of cloning vectors used in genetic engineering, including plasmids, phages, and cosmids, and how selectable markers and origins of replication enable gene cloning.
Cloning vectors must be able to replicate within a host cell to ensure the propagation of the inserted gene.

Antibiotic resistance genes help in selecting transformed cells by allowing only recombinant cells to survive in antibiotic-containing media.

Plasmids are small, circular, extra-chromosomal DNA molecules that can replicate independently and are commonly used as cloning vectors.
