C) Is the correct answer I believe, unless you want to flush the chemicals down the sink and then have a reaction with them the next time you go swimming in a lake and find them there.
Answer:
E) horizontal gene transfer
Explanation:
Horizontal gene transfer(HGT) is mainly seen in bacteria. Bacteria exchange their genetic material from the horizontal gene transfer method. There are three methods in HGT- conjugation, transduction, and transformation.
In conjugation, the bacteria exchange their plasmid through sex pilus. In transformation, bacteria take up other's genetic material from its environment and in transduction virus-mediated gene transfer occurs.
Therefore in bacteria and nucleus, the genetic material exchange can occur only through HGT.
