Cauliflower mosaic virus contains

Explanation

a)ss RNA (single-stranded RNA): This option is incorrect for Cauliflower mosaic virus. While there are RNA viruses, this virus has a ds DNA genome. b)ds RNA (double-stranded RNA): This option is not applicable to Cauliflower mosaic virus as it is a DNA virus, not an RNA virus. c)Cauliflower mosaic virus contains ds DNA (double-stranded DNA). It is a pararetrovirus, meaning it has a double-stranded DNA genome that can be reverse transcribed into RNA. This property makes it distinct from typical retroviruses like HIV, which have an RNA genome. d)ss DNA (single-stranded DNA): Cauliflower mosaic virus does not contain single-stranded DNA. It has a double-stranded DNA genome. So, the correct answer is indeed ds DNA, as Cauliflower mosaic virus is known for its double-stranded DNA genome.
