Question
What is true of DNA, but not RNA? Check all that apply.Check All That ApplyThere is an -OH group at C2.There is an -OH group at C2.Thymine is present as a nitrogenous base.Thymine is present as a nitrogenous base.Detection occurs using Dische diphenylamine.Detection occurs using Dische diphenylamine.Cytosine is present as a nitrogenous base.
Solution
The following statements are true of DNA, but not RNA:
-
There is no -OH group at C2: In DNA, the sugar is deoxyribose, which lacks an -OH group at the 2' position. In contrast, RNA has a ribose sugar, which has an -OH group at the 2' position.
-
Thymine is present as a nitrogenous base: In DNA, the nitrogenous bases are adenine, guanine, cytosine, and thymine. In RNA, thymine is replaced by uracil.
-
Detection occurs using Dische diphenylamine: This is a test specifically for DNA. It does not detect RNA.
The statement "Cytosine is present as a nitrogenous base" is not exclusive to DNA. Cytosine is a nitrogenous base that is present in both DNA and RNA.
