Question

Which of the following key factors makes the plasmid a good vector in genetic engineering?

• A. Plasmid has an Ori sequence
• B. It is self replicating
• C. It has ability to carry a foreign gene
• D. Its ability to cause infection

Answer 1

Answer: (A), (B), (C)

It has ability to carry a foreign gene

Plasmid, found in the bacteria, has the ability to carry foreign gene. Additionally it also has an ori sequence that helps in the replication of the plasmid, making it a self replicating entity. Thus a plasmid can be used as an efficient vector in genetic engineering.
