D) This is an example of facilitated diffusion.this is through byvthe family of hexoses transporter
The human genome is the entire set of genetic information needed in a 'regular' human, so scientists have mapped out all 23 chromosomes information.
Gene transfer via transduction could be beneficial if the donor has a new gene that could produce a useful protein. This protein could be an enzyme with various effect like
1 digesting food(fermentation),
2 digesting drug(drug resistance) or
3 toxin that could kill the nearby cells(to decrease food competition).
It is autosomal. However I'm unsure what you would do to explain.
