Answer:
1. I and IV
2. II and III
3. I and II
Step-by-step explanation:
The complete question is
Virus T C U G A
I 0 12 9 12 9
II 23 16 0 16 23
III 34 42 0 18 39
IV 0 24 35 27 17
The relative amounts of each nucleotide base are tabulated here for four different viruses.
Which virus has a single stranded DNA genome, a single stranded RNA genome, and which has a double stranded RNA genome?
Solution
RNA has "U" instead of T in its nucleotide sequence. Hence, both I and IV are RNA
DNA has T instead of U and hence both II and III are DNA
Virus I and II are double stranded RNA because they both have equeal number of base pair group
A=T and C=G
