Question

1. what are the components of the molecule shown in the diagram? clear all i&ii i,ii,&iii i&iii i,ii,&iv

Explanation:

To solve this, we analyze the DNA structure:

Step 1: Identify DNA components

DNA is a double - helix made of nucleotides. Each nucleotide has three parts:

• I (Phosphate group): Forms the backbone.
• II (Sugar - deoxyribose): Also part of the backbone.
• III (Nitrogenous base): Forms the rungs (A, T, C, G).

Step 2: Evaluate the options

The diagram shows a DNA molecule, so its components include phosphate (I), deoxyribose (II), and nitrogenous bases (III). Thus, the correct option includes I, II, and III.

Answer:

I, II, & III (the option with "I, II, & III" text)
