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.
in the scientific method, questioning is the first step
A DNA Fingerprint is a pattern of dark bands on photographic film that is made when DNA fragments are separated by Gel electrophoresis and tagged. Every human has their own unique fingerprints which will leave its trace to whatever objects we touched and our Law enforce held the database of all legal citizen's fingerprints
