Question

Which of the following is true regarding taking up of plasmid DNA in the bacterial cells?

(a) There are more chances of having two plasmids in a single cell

(b) There are more chances of having a single plasmid in one cell

(c) Uptake upto two plasmids is possible but not more than that

(d) Both are taken up with the same efficiency

I have been asked this question in my homework.

My enquiry is from Cloning using a Simple Plasmid and Alpha Complementation in chapter Simple Cloning of Genetic Engineering

Answer 1

Correct option is (b) There are more chances of having a single plasmid in one cell

To elaborate: There are more chances of having a single plasmid in one cell. But there are possibilities of having two plasmids in a single cell but the chances are less.
