    Watched this video to understand what the term "DNA Cloning" means and how that's done with the help of recombinant DNA technology.
    Got to know that it's reproducing of the desirable genes/sections of DNA with the help of certain restriction enzymes, DNA ligase, and the host bacteria that supplies plasmids to attach the target genes and then reproduces them.
    This video also clarifies the question - "How to engineer microorganisms?" - for which I have seen other videos earlier (insulin production as a case in point)

    I was wondering the following, this video tells me that DNA is taken from one organism and put into another organism's plasmid so that that organism can go and create a desired protein. My question is then, does the bacteria know how to splice the introns and exons when it's creating the desired protein. Much more logical to me would be that they take ripe mRNA, (already spliced correctly) reverse transcript that and put it in the plasmid, since bacteria don't have introns and exons.

      Because we are using plasmids which carry the factors coding for resistance against some antibiotics and the scientists who perform these experiments are well aware of the plasmids and the resistance they have ..and as the replication occurs in the E coli this gets amplified...
