Can someone help me label these. The options are Deoxyribose sugar, guanine, phosphate, and adenine.

1. Phosphate

2. Guanine

3. Deoxyribose sugar

4. Adenine

Explanation: Remember the base pairing rules: cytosine with guanine and adenine with thymine, so whenever there's cytosine, there's guanine, and vice versa (the rules are a little different with adenine and thymine in terms of RNA). In the phosphate-sugar backbone, the phosphate will always be on the outside, and the sugar will always be found attached to the nitrogenous base.

Hope this helps,

where is the option.let me know

supercell thunderstorms are perhaps the most violent of all thunderstorm types, and are capable of producing damaging winds, large hail, and weak-to-violent tornadoes
