Solution
- Vectors are DNA molecules that transport and reproduce foreign DNA segments within the host cell.
- Vectors include plasmids, bacteriophages (M13, lambda virus), cosmids, phagemids, BACs, YACs (yeast artificial chromosomes), transposons, baculoviruses, and mammalian artificial chromosomes (MACs).
- Plasmid vectors (pBR 322, pUC, Ti plasmid) and bacteriophages (lambda phage, M13 phage) are the most often utilised vectors.
