Question

DNA and RNA are structurally similar in some ways, but different in others. Identify whether each of the following statements applies to DNA, RNA, both or neither.

1. It can contain the pyrimidine cytosine.
2. It can contain the pyrimidine uracil.
3. This contains the sugar 2'-deoxyribose.
4. In terms of base composition, the %A = %C.
5. This contains the sugar ribose.
6. The bases are attached to sugars in a beta-N-glycosidic linkage.
7. It contains equal amounts of guanine and cytosine.
8. Sugars are connected with a 3'-5' phosphodiether link.

Answer 1

Step-by-step explanation:

1. It can contain the pyrimidine cytosine - Both

2. It can contain the pyrimidine uracil - RNA

3. This contains the sugar 2'-deoxyribose - DNA

4. In terms of base composition, the %A = %C - Neither: %A = %T

5. This contains the sugar ribose - RNA

6. The bases are attached to sugars in a beta-N-glycosidic linkage - Both

7. It contains equal amounts of guanine and cytosine - Both

8. Sugars are connected with a 3'-5' phosphodiether link - Neither: they are connected by a 3'-5' phosphodiester link
