Question

Thank you for your help :) Which of the following is a way to distinguish between DNA and RNA? The number of carbon atoms in the ribose of DNA is 5; it is only 4 in the ribose of RNA. The nitrogenous bases of RNA form hydrogen bonds with one another, but those of DNA do not DNA contains the nitrogenous base Adenine, Cytosine, Uracil and Guanine, while RNA contains Adenine, Cytosine Thymine and Guanine. There is an OH group on the 3' carbon of the RNA sugar but not on the 3 carbon of the DNA suga

Explanation / Answer

The first option is wrong because both have 5 carbon sugars.

Option 2 is also wrong because hydrogen bonding between bases is present in both

DNA has ATCG and RNA AUCG so its the opposite of what is given

The option 4 is correct as DNA has deoxy ribose and RNA does not.
