Answer 1

The fourth major category of important macromolecules is nucleic acids. Two types of nucleic acids are: **DNA (Deoxyribonucleic Acid)** and **RNA (Ribonucleic Acid)**.

b. Nucleic acids are macromolecules that hold the genetic information to build and maintain an organism.

c. The building blocks of nucleic acids are **nucleotides**.

d. A nucleotide is made up of three parts:
i. A phosphate group (PO₄)
ii. A sugar (the sugar in DNA is deoxyribose, and the sugar in RNA is ribose)
iii. A nitrogen-containing molecule called a **nitrogenous base**.

iv. Each nucleotide (in DNA) can contain one of different bases. These bases are:
- **Adenine (A)**
- **Thymine (T)**
- **Cytosine (C)**
- **Guanine (G)**
