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.

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

the potatoes have high sugar concentrations and although these potatoes were different we could seethe effects that their sugar concentrations had in different environments. for example, the potatoes in sample a, were placed in pure water. this created a hypertonic environment and caused the potatoes to draw in water from its surroundings. we saw the opposite happen with the potatoes in sample b when placed in the sodium chloride solution. the potatoes in this case were in a hypotonic solution and therefore lost water to their surroundings.
