1. What are the constituents of DNA?

A. Sugars and lipids
B. Proteins and sugars
C. Sugars, phosphates, and nitrogenous bases
D. Lipids, nitrogenous bases, and proteins

MY ANSWER IS C.

correct

Thank you so much

When you do a push-up from the floor, what kind of movement describes the motion of your elbow?

A. Flexion
B. Abduction
C. Rotation
D. Extension

My answer is D. I could be wrong

Now that I think about it, it is A and not D

Correct, the constituents of DNA are sugars, phosphates, and nitrogenous bases.

To arrive at this answer, you can start by recalling some basic knowledge about DNA. DNA (deoxyribonucleic acid) is a molecule that carries the genetic information in most living organisms.

Next, you can eliminate the options that don't include the correct constituents.
- Option A (Sugars and lipids) is incorrect because lipids are not part of DNA's structure.
- Option B (Proteins and sugars) is incorrect because proteins are not part of DNA's structure.
- Option D (Lipids, nitrogenous bases, and proteins) is incorrect because lipids and proteins are not part of DNA's structure.

By process of elimination, you are left with option C, which states that sugars, phosphates, and nitrogenous bases are the constituents of DNA. Sugars (deoxyribose) and phosphates make up the backbone of DNA's double helix structure, while nitrogenous bases (adenine, thymine, cytosine, and guanine) pair up to form the "rungs" of the DNA ladder.
