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 field of application?Cheminformatics and computational chemistry
2. What is the core principle?The Similar Property Principle
3. Why do scientists use chemical similarity?It helps them guess how a new molecule will behave, like whether it could be a medicine or a useful material, so they can test only the most promising ones.
4. How do computers find similar molecules?Computers use fingerprints that list the features of a molecule, then compare these fingerprints with a score called the Tanimoto coefficient to see how close they are.

Cheminformatics: An interdisciplinary field that develops methods for storing, retrieving, and analyzing chemical information.
Molecular Fingerprint: A computational representation of a molecule's structural or chemical features.
Tanimoto Coefficient: A common statistical measure used to quantify the similarity between two binary data sets, like molecular fingerprints.
