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.

Please do not give me the answers from other Chegg's question because my question is different from them

Select answer 1. It can contain the purine guanine. Select answer 2. It can contain the pyrimidine uracil. 3. This contains the sugar 2'-deoxyribose. Select answer 4. In terms of base composition, the %T %G. Select answer 5. This contains the sugar ribose. Select answer 6. Th Select answer glycosidic linkage. 7. It contains equal amounts of purines and Select answer la pyrimidines. 8. Sugars are connected with a 3-5' Select answer phosphodiether link.

Explanation / Answer

1. both

DNA and RNA contains nitrogen bases having purine and pyrimidine as core structure.

DNA has four nitrogen bases, Adenine, Thymine, Cytosine and Guanine.

RNA also has four nitrogen bases. Instead of Thymine RNA has Uracil in it.

Adenine (A), Guanine (G) are purine bases. Cytosine (C), Thymine (T), Uracil (U) are pyrimidine bases.

2. RNA

RNA also has four nitrogen bases. Instead of Thymine RNA has Uracil in it.

3. DNA

As the name itself suggests DNA (Deoxyribonucleic acid), DNA contains the sugar deoxyribose.

4. neither

In DNA or RNA the % of thymine is not equal to the % of Guanine.

5. RNA

As the name itself suggests RNA (ribonucleic acid), RNA contains the sugar ribose.

6. both

Both in DNA and RNA, the bases are attached to sugar in a beta-N-glycosidic linkage.

7. DNA

In DNA purine and pyrimidine bases are equal in number.

8. neither

In DNA or RNA sugars are connected with 3'-5'phosphodiester link (not with the ether link).
