Which one of the following is not applicable to RNA?

Step-by-step solution

Erwin Chargaff’s rules: Chargaff along with his colleagues, performed base composition studies and put forward certain generalizations for double stranded DNA, called as Chargaff’s rule (Not applicable for single stranded DNA or RNA). i) Purines and pyrimidines occur in equal amounts. ii) Purines found in DNA are adenine and guanine. Pyrimidines of DNA are thymine and cytosine. A + G = T + C iii) A + G T + C   =   1 this value is constant for all species. iv) The base ratio A + T G + C
