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
A. There are no introns in the genome
B. The introns contain the recognition sites and have already been spliced out
C. All of restriction fragments are too small to detect
D. Restriction endonucleases do not cut RNA, and this virus has an RNA genome
Answer: Option D
A. No recombinant molecule will ever be detected
B. Both linear and circular molecules will replicate equally well
C. None of the plasmids will express the antibiotic resistance gene located on the plasmid
D. The circular molecules will be amplified by the cells
A. Addition of lactose to the medium
B. Removal of all glucose from the medium
C. Addition of excess glucose to the medium
D. Addition of allo-lactose to the medium
A. Both [A] and [R] are true and [R] is the correct reason for [A]
B. Both [A] and [R] are true but [R] is not the correct reason for [A]
C. Both [A] and [R] are false
D. [A] is false but [R] is true
A. P only
B. P, R and S only
C. P and R only
