Question:
Which of the following is not a component of DNA?
Which of the following is not a component of DNA?
Updated On: Nov 4, 2024
- Thiamine
- Adenine
- Guanine
- Cytosine
Hide Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Thiamine is a vitamin (Vitamin B1) and not a nucleotide base. DNA consists of the bases adenine, guanine, cytosine, and thymine. Remembering the difference between thymine (a DNA base) and thiamine (a vitamin) is crucial in such questions.

Aldehydes are generally more reactive than ketones in nucleophilic addition reactions due to steric and electronic reasons. Sterically, the presence of two large groups in ketones hinders the attack of nucleophile to carbonyl carbon than in aldehydes. Electronically, aldehydes are more reactive than ketones because two alkyl groups reduce the electrophilicity of the carbonyl carbon more effectively than in the former- CUET (UG) - 2024

The transition metals are very hard and have low volatility. Their melting and boiling points are high. In any row, the melting points of these metals rise to a maximum at d5 and fall regularly as atomic number increases. The high melting points of these metals are attributed to the involvement of greater number of electrons from (n– 1)d in addition to ns electrons in the interatomic metallic bonding.- CUET (UG) - 2024
