| 21. | The 5'carbon of this deoxyribose is again linked to the 3'carbon of the next, and so forth.
|
| 22. | When connected into DNA, a covalent bond is formed between deoxyribose sugar and the bottom left nitrogen, so removing the hydrogen.
|
| 23. | The 5-carbon sugar is indicated with or without the lowercase " d " indicating deoxyribose if included or ribose if not.
|
| 24. | The backbone of RNA and DNA are structurally similar, but RNA is single stranded, and made from ribose as opposed to deoxyribose.
|
| 25. | The outside of the DNA chain has a backbone of alternating deoxyribose and phosphate molecules, and codes for inheritance are inside the helix.
|
| 26. | Adenosine is adenine reacted with ribose as used in RNA and ATP; deoxyadenosine adenine attached to deoxyribose, as is used to form DNA.
|
| 27. | "' Deoxyguanosine "'is composed of the purine nucleobase guanine linked by its N9 nitrogen to the C1 carbon of deoxyribose.
|
| 28. | This reaction that removes the 2-OH of the ribose sugar to generate deoxyribose is not affected by the bases attached to the sugar.
|
| 29. | In the backbone of DNA the 5'carbon of one deoxyribose is linked to the 3'carbon of another by a phosphate group.
|
| 30. | It is similar to guanosine, but with one hydroxyl group removed from the 2'position of the ribose sugar ( making it deoxyribose ).
