Question

Some mutations are present which assist the uptake of DNA. Which of the statement is incorrect for it?

(a) deoR is such a mutation which assists the uptake of DNA

(b) It is a transcriptional regulator

(c) It is having DNA binding activity

(d) It controls the expression of a set of genes involved ribonucleoside catabolism

I got this question during a job interview.

Asked question is from Transformation and Hosts topic in portion Simple Cloning of Genetic Engineering

Answer 1

The correct choice is (d) It controls the expression of a set of genes involved ribonucleoside catabolism

For explanation: There are various factors which affect the uptake of DNA by the cells. deoR is an example of such a mutation which assists the uptake of DNA. It is a transcriptional regulator and is having DNA binding activity. It controls the expression of a set of genes involved in deoxyribonucleoside catabolism.
