Both a wine maker and a molecular biologist who had developed a recombinant vaccine claim to be biotechnologists. Who in your opinion is correct?

Credit for the construction of the first recombinant $DNA$ is given to:

The technique to alter the chemistry of genetic materials, $DNA$ and $RNA$, to introduce these into host organisms and change the phenotype of the host is:

What is the fate of a piece of $DNA$ carrying only the gene of interest which is transferred into an alien organism?
$A$. The piece of $DNA$ would be able to multiply itself independently in the progeny cells of the organism.
$B$. It may get integrated into the genome of the recipient.
$C$. It may multiply and be inherited along with the host $DNA$.
$D$. The alien piece of $DNA$ is not an integral part of the chromosome.
$E$. It shows the ability to replicate.
Choose the correct answer from the options given below:

The critical research areas of biotechnology are:
$I$. Providing the best catalyst as an improved organism,usually a microbe or pure enzyme.
$II$. Creating optimal conditions through engineering for a catalyst to act.
$III$. Downstream processing technologies.
$IV$. Multiple Ovulation Embryo Transfer Technology $(MOET)$.
