You have cut the genome of a double-stranded viral genome with a restriction endonuclease and electrophoresed the products on an agarose gel. You observe only one band on the gel, equivalent to the size of the genome. This is because
-
- there are no introns in the genome
- the introns contain the recognition sites and have already been spliced out
- all of restriction fragments are too small to detect
- restriction endonucleases do not cut RNA, and this virus has an RNA genome
Correct Option: D
RE doesn’t recognize RNA.
