Question

which vector can clone only a small fragment of DNA ?? 1) plasmid 2) cosmid 3) bacterial artificial chromosome 4) yeast artificial chromosome

Answer 1

Flag Answer Ans is (1) Plasmid can clone only a small fragment of DNA (0.5-8 kb) other can clone large fragment of DNA like. Cosmid (30 - 45 kb) BAC (50 - 300 kb) YAC (1000 - 2500 kb) Forum Sorathiya Teacher 1.5k

Answer 2

Plasmid is the vector which clones only a small fragment of DNA.

Explanation:

The main function of vectors is to replicate the DNA sequence inserted in them. Usually in the field of genetic engineering the following five cloning vectors are used:

• Plasmids

• Bactriophages

• Viruses

• BAC

• YAC

Among the above mentioned vectors, Plasmid is used to clone small fragments of DNA. It is because it is small in size and is double stranded in nature.
