Question:
Nucleotides are composed of:
Nucleotides are composed of:
Show Hint
Nucleotides differ from nucleosides as they contain a phosphate group, which is essential for forming the DNA and RNA backbone.
Updated On: Feb 25, 2025
- Pentose sugar and phosphoric acid
- Nitrogenous base, pentose sugar, and phosphoric acid
- Nitrogenous base and phosphoric acid
- Pentose sugar and nitrogenous base
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Nucleotides are the fundamental building blocks of DNA and RNA. Each nucleotide consists of:
- A nitrogenous base (purines: adenine, guanine; pyrimidines: thymine, cytosine, uracil)
- A pentose sugar (deoxyribose in DNA, ribose in RNA)
- A phosphate group, which forms the backbone of the nucleic acid structure.
These components enable genetic information storage and transmission.
