Question

Nitrogen is NOT an essential constituent of
1. Chlorophyll
2. RNA
3. DNA
4. Carbohydrate

Answer 1

Correct Answer - Option 4 : Carbohydrate

The correct answer is Carbohydrate.

• Nitrogen is the chemical element with the symbol N and atomic number 7.
• It is the most abundant element in Earth's atmosphere: approximately 78% of the atmosphere is nitrogen.
• The chemical structures of carbohydrates contain carbon, hydrogen, and oxygen atoms. It does not have nitrogen.
• Nitrogen is a major component of chlorophyll. Nitrogen enables the plant to capture sunlight energy by photosynthesis, driving plant growth and grain yield.
• Ribonucleic acid is a polymeric molecule essential in various biological roles in coding, decoding, regulation and expression of genes.
• RNA consists of four nitrogenous bases: adenine, cytosine, uracil, and guanine.
• DNA (Deoxyribonucleic acid) is the hereditary material in humans. It is a nucleic acid that contains the genetic instructions for the development and function of living things.
• The nitrogenous bases in DNA are adenine (A), guanine (G), thymine (T), and cytosine (C).
