You've described the basic structure of a nucleotide, which is a fundamental building block of DNA. Each nucleotide consists of three components:
1. **Phosphate Group**: Represented as a blue circle. It is attached to the sugar and serves to link the nucleotides together through phosphodiester bonds, forming the backbone of the DNA strand.
2. **Deoxyribose Sugar**: Shown as a tan pentagon. This five-carbon sugar distinguishes deoxyribonucleic acid (DNA) from ribonucleic acid (RNA), which contains ribose sugar instead.
3. **Nitrogenous Base**: Typically shown in various colors to represent different types. There are four nitrogenous bases in DNA:
- Adenine (A), which pairs with Thymine (T)
- Thymine (T), which pairs with Adenine (A)
- Cytosine (C), which pairs with Guanine (G)
- Guanine (G), which pairs with Cytosine (C)
Together, these components form nucleotides, which connect in a chain to create the DNA double helix structure, encoding genetic information necessary for biological functions and inheritance. If you have any specific questions about nucleotides or DNA structure, feel free to ask!
