Answer:
Option (e).
Step-by-step explanation:
RNA is present as genetic material in some viruses only. RNA is generally a single stranded molecule that contains the oxyribose sugar and the uracil as nitrogenous base instead of thymine.
The non Watson crick base pairing has been noticed in the different forms of DNA. The RNA uses metals to stabilize its folding. The interactions involve more than two nucleotides in the RNA molecule.
Thus, the correct answer is option (e).
