Question

Write a short note on vectors.

Answer 1

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