You have created a recombinant DNA molecule by ligating a gene to a plasmid vector
The experiment will not likely to be affected as recombinant DNA molecule is circular closed, with no free ends. Hence, it will not be a substrate for exonuclease enzyme which...

The restriction enzymes that are used in construction of recombinant DNA molecule are endonuclease
If the restriction enzymes would cut DNA at random sites instead of at specific sites, then the DNA fragments obtained will not have ‘sticky ends’. In the absence of sticky...

What would happen when you grow a recombinant in a bioreactor but forget to add antibiotic to the medium in which the recombinant is growing.
In the absence of antibiotic, there will be no pressure on recombinants to retain the plasmid (containing the gene of your interest). Since, maintaining a high copy number of plasmids...

Name and explain the technique that heips in the separation of DNA fragments for DNA recombinant technology experiments.
Gel electrophoresis , Since DNA fragments are negatively charged , they move towards anode (under an electric field ) through a medium / matrix / agarose gel , The fragments...
