Micro-injection is a method used to
If a person obtains transformants by inserting a recombinant DNA within the coding sequence of enzyme -galactosidase, he will separate out recombinants from non-recombinants by which of the following observations?
In the process of insertional inactivation ________________.
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 -galactosidase enzyme and the colonies do not produce any colour.
Direct visual selection method for the selection of recombinant host cells on the basis of their inability to produce colour in the presence of chromogenic substrate can be applied if the vector used is a
Changes in transcription after linking the cloned DNA of the putative promoter/enhancer region to cloned DNA of the coding region of an unrelated gene, can be measured rapidly with a high degree of sensitivity using.
