Assertion: All expression vectors are cloning
vectors and vice versa.
Reason: Expression vectors have at least the
regulatory sequences i.e., promoters, operators,
ribosomal binding sites, etc. having optimum
function in the chosen control but not origin of
replication.
vectors and vice versa.
Reason: Expression vectors have at least the

Assertion: Special methods are used for
transformation i.e., incorporation of recombinant
DNA into molecule.
Reason: DNA is a hydrophilic molecule. Proteins are removed by treatment with Enzyme isolated from Thermus aquaticus bacterium is used in plasmids used in genetic engineering is obtained from Which one of the following hydrolyses internal phosphodiester bonds in a polynucleotide chain? Which one of the following is used as vector for cloning genes into higher organisms?
