Question

One of the key factors, which makes the plasmid the vector in genetic engineering is that ______.

विकल्प

• it is resistant to antibiotics

• it is resistant to restriction enzymes

• its ability to carry a foreign gene

• its ability to cause infection in host

Answer 1

One of the key factors, which makes the plasmid the vector in genetic engineering is that its ability to carry a foreign gene.

Explanation:

A plasmid can carry a foreign gene into a host cell and replicate there, making it useful as a vector. Antibiotic-resistance genes can serve as selectable markers, but resistance itself is not the key vector property.
