What is insertional inactivation?

Which of the following enzyme will get inactivated in insertional inactivation

Which of the following enzyme will get inactivated in insertional inactivation

For selection of recombinants, insertional inactivation of antibiotic marker has been superseded by insertional inactivation of a marker gene coding for a chromogenic substrate. Give reasons.

For selection of recombinants, insertional inactivation of antibiotic marker has been superseded by insertional inactivation of a marker gene coding for a chromogenic substrate. Give reasons.

For selection of recombinants, insertional inactivation of antibiotic marker has been supercoded by insertional inactivation of a marker gene coding for a chromogenic substrate. Give reasons.

Read the given statements and select the correct option Statement 1 : In insertional inactivation, blue colour produced by bacterial colonies indicates that the plasmid does not have an insert into the bacterial genome. Statement 2: Presence of insert results into insertional inactivation of beta -galactosidase enzyme and the colonies do not produce any colour.

How is insertional inactivation of an enzyme used as a selectable marker to differentiate recombinants from non-recombinants?
