4 properties of vectors - correct answer- 1.most
important property of a vector is self-replication, and
once in a cell, the vector must be capable of replicating.
2.Vectors must be able to recognize sequence for a
restriction enzyme, a unique genetic marker that we can
identify once enters the host cell
3.should be small in comparison to host chromosome
4. Plasmids, artificial chromosomes, and viruses are used
as vectors.
