Question

Why are engineered vectors preferred by biotechnologists for transferring the desired genes into another organisms?

Answer 1

Answer:

So, genetically engineered vectors are preferred by biotechnologists. Vectors are also modified for other reasons. For example: Ti plasmid can be modified into a cloning vector by removing the genes responsible for pathogenicity and inserting desired genes such as disease resistance..

Answer 2

Answer:

Engineered vectors are preferred by biotechnologists because they help in easy linking of foreign DNA and selection of recombinants from non-recombinants.
