During insertional inactivation, the presence of a chromogenic substrate gives blue coloured colonies if the plasmid in the bacteria does not have an insert. The blue colour is produced by the enzyme 1) α -glucosidase 2) restriction endonuclease 3) β -galactosidase 4) Taq polymerase

The presence of a chromogenic substrate gives blue coloured colonies of bacteria. Insertional inactivation would stop product of which of the following enzyme such that colonies do not produce any colour.

True and false : In insertional inactivation process alien gene introduced in ori. Sequence.

In insertional inactivation of beta -galactosidase gene, the bacteria in white colonies have

Assertion: The inactivation of any vector gene due to insertion of desired gene called as insertional inactivation Reason :Some time restriction sites are also present in between the gene sequence of vector

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. A) Both statements 1 and 2 are correct B) statement 1 is correct but statement 2 is incorrect C) statement 1 is incorrect but statement 2 is correct D) Both statements 1 and 2 are incorrect

For selection of recombinants, insertional inactivation of antibiotic marker has been superseded by insertional inactivation of a marker gene coding for a chromogenic substrate.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

In the process of insertional inactivation 1) a recombinant DNA is inserted within the coding sequence of enzyme β -galactosidase, resulting in inactivation of the enzyme 2) a recombinant DNA is inserted within the coding sequence of proteins involved in the replication of the plasmid 3) a recombinat DNA is inserted within the recongnition site for EcoRl 4) none of these

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