1. Nitrogenous Base: This is a molecule with nitrogen in its structure. There are five main nitrogenous bases found in DNA:
* Adenine (A)
* Guanine (G)
* Cytosine (C)
* Thymine (T)
* Uracil (U) - This is found in RNA, not DNA.
2. Pentose Sugar: This is a five-carbon sugar molecule. In DNA, the specific sugar is deoxyribose.
3. Phosphate Group: This is a molecule containing phosphorus and oxygen atoms. It provides the negative charge to the nucleotide and plays a crucial role in forming the backbone of the DNA molecule.
The bond between the sugar and the phosphate group is called a phosphodiester bond, and it forms the backbone of the DNA molecule. The nitrogenous bases stick out from the backbone and pair with complementary bases on another strand of DNA.
Here's a simple way to remember it:
* Nitrogenous base
* Sugar
* Phosphate
