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
