Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the chemical classification?Purines (Adenine, Guanine) and Pyrimidines (Cytosine, Thymine, Uracil)
2. What is the therapeutic relevance?Nucleobase analogs are key components in antiviral and anticancer drug development
3. What are nucleobases and why are they important?Nucleobases are tiny building blocks inside DNA and RNA that carry genetic information and help make proteins.
4. How many types of nucleobases are there and what are they called?There are five: adenine, guanine, cytosine, thymine, and uracil. Adenine and guanine are purines with two rings, the others are pyrimidines with one ring.

Heterocyclic Aromatic Compound: An organic molecule containing a ring structure with at least one atom other than carbon.
Complementarity: The principle that specific bases in nucleic acids pair with each other (A with T/U, G with C).
Nucleoside Analog: A molecule that mimics a nucleoside and can interfere with nucleic acid synthesis or function.
