Statement I: In order to link the alien DNA, the vector needs to have very few, preferably single, recognition sites for the commonly used restriction enzymes.
Statement II: Presence of more than one recognition sites within he vector will generate several fragments, which will complicate the gene cloning.
Text Solution
Verified by ExpertsA
Statement I: Correct
A cloning vector should have very few, preferably a single recognition site for a restriction enzyme so that it is cut at only one location.
Statement II: Correct
If a vector contains multiple recognition sites, digestion with the restriction enzyme will produce several fragments, making cloning difficult.
