Question 31 (c) - Choice 1 [Case Based] - Chemistry CBSE Class 12 Sample Paper for 2023 Boards - Solutions - Solutions to CBSE Sample Paper - Chemistry Class 12

Last updated at April 16, 2024 by Teachoo

The sample of a virus was tested and it was found to contain 20% adenine, 20% thymine, 20 % guanine and the rest cytosine. Is the genetic material of this virus (a) DNA- double helix (b) DNA-single helix (c) RNA? What do you infer from this data?

Answer:

A = T = 20%

But G is not equal to C so double helix is ruled out.

The bases pairs are ATGC and not AUGC so it is not RNA

The virus is a single helix DNA virus
