DNA vs RNA

[bebe1018_87]

which apply to dna, which to rna, which to both and, which to neither. are my answers correct?

 

1. contains sugar 3'- deoxyribose--> neither

2. containes sugar 2'-deoxyribose--> dna

3. secondary structure is primarily a double helix--> dna

4. sometimes contains the nucleoside pseudouridine--> rna

5. contains the purine guanine--> both

6. sugars are connected with a 3'-5'phosphodiether link--> neither b/c its a phosphodiester not ether

7. in base composition, %A=%T --> DNA

8. bases are attached to sugars in a beta-glycosidic linkage. --> both

9. sometimes shows hydrogen bonding between a sugar hydroxyl and a base--> both

10. contains the pyrimidine uracil--> rna

11. in base composition, %A=%C--> neither

 

thank u so much!
