The correct Answer is:
To answer the question, "What are the basic components of a nucleotide?", we can break down the information into clear steps: ### Step-by-Step Solution: 1. **Understanding Nucleotides**: - Nucleotides are the basic building blocks of nucleic acids, which include DNA (Deoxyribonucleic Acid) and RNA (Ribonucleic Acid). 2. **Identifying the Components**: - A nucleotide consists of three main components: 1. **Nitrogenous Base**: This can be one of the following: - Adenine (A) - Guanine (G) - Cytosine (C) - Thymine (T) - only in DNA - Uracil (U) - only in RNA 2. **Pentose Sugar**: This is a five-carbon sugar that can be: - Deoxyribose (in DNA) - Ribose (in RNA) 3. **Phosphate Group**: This is a phosphate molecule that is attached to the sugar. 3. **Summarizing the Components**: - Therefore, the basic components of a nucleotide are: - Nitrogenous Base - Pentose Sugar - Phosphate Group 4. **Conclusion**: - The correct answer to the question is that nucleotides are composed of a nitrogenous base, a pentose sugar, and a phosphate group.
