An insertion sequence…?
I think the answer is E, but I’m not sure.
An insertion sequence:
a) carries a gene only for transposase between two invertetd repeats
b)may transpose genes for antibiotic resistance to R plasmids
c) involves the exchange of homologous regions of DNA
d)is nessecary for the F plasmid to incorporate into the bacterial chromosome to form an Hfr cell
e) cosists of an inverted repeat sandwhiched between two direct repeats
(im not trying to ripp off answers here, I just need help)
