Detailed explanation-2: -A vector is a DNA molecule that is used as a vehicle to artificially carry the foreign genetic material into another cell to be replicated or expressed. Examples include plasmid, cosmid, Lambda phages, etc. BAC (Bacterial Artificial Chromosome) and YAC (Yeast Artificial Chromosome) are cloning vectors.
Detailed explanation-3: -Abstract. Bacteriophage lambda has been in use as a cloning vector for over 25 years, and has been used extensively as an expression vector. The efficiency of packaging and infection, and the simplicity of plaque screening are advantages of lambda as a cloning vector.
Detailed explanation-4: -A series of plasmid expression vectors, which support the regulated and efficient expression of genes in Escherichia coli, have been constructed. The vectors consist of a DNA replication origin cassette, a promoter cassette, an efficient ribosome binding site together with a polylinker region and a lacZ gene.
