Given below is the percentage of nitrogenous bases present in four different samples of the genetic material. Identify, which sample belongs to an RNA virus
View answer and explanation
Correct option: C
Sample C : U – 32%, G – 23%, C – 23%, A – 32%
Option C (U – 32%, G – 23%, C – 23%, A – 32%) is correct because RNA contains uracil (U) instead of thymine (T), and the percentages of bases do not necessarily follow Chargaff's rules (A=T, G=C) as it is single-stranded.
