medium
Which of the following key factors, makes plasmid, the vector in genetic engineering?
A
It is resistant to antibiotics
B
It is resistant to restriction enzymes
C
Its ability to carry a foreign gene
D
Its ability to cause infection in the host
Solution
Plasmids, cosmids or bacteriophages can be used as vector in genetic engineering. Plasmids are most widely used circular, extrachromosomal $DNA$ segments seen in the bacterial cells. They carry a foreign gene or desired gene to the host. The size of plasmids ranges from $1 \times 10^{6}$ to $200 \times 10^{6}$ daltons
