In molecular biology, a vector is a DNA molecule that carries a DNA segment into a host cell. Vectors are often plasmids or viruses. Plasmids are small, circular, double-stranded DNA molecules that are distinct from a cell's chromosomal DNA. They are found in bacterial cells and some eukaryotes. Plasmids are self-replicating DNA molecules that have a high copy number and possess antibiotic-resistant genes. Plasmid vectors contain an origin of replication that allows for semi-independent replication of the plasmid in the host. Phagemids are plasmid vectors that contain an origin of...

Vectors are often plasmids or viruses.
Plasmids are small, circular, double-stranded DNA molecules that are distinct from a cell's chromosomal DNA. They are found in bacterial cells and some eukaryotes. Plasmids are self-replicating DNA molecules that have a high copy number and possess antibiotic-resistant genes. Plasmid vectors contain an origin of replication that allows for semi-independent replication of the plasmid in the host. Phagemids are plasmid vectors that contain an origin of replication from a phage, in addition to that of the plasmid.
