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 primary data types?DNA, RNA, and peptide (protein) sequences
2. What is the core analytical goal?To infer biological features, function, structure, and evolutionary relationships
3. How do scientists read DNA and RNA?Scientists use machines that can read the letters in DNA and RNA very fast and accurately. The first machines were slow and manual, but new machines called next‑generation sequencers can read millions of letters in just a few hours.
4. Why is sequence analysis important for medicine?Sequence analysis helps doctors find genetic problems, spot germs that cause illness, and design medicines that fit each person’s own genes. It can also help scientists understand diseases like cancer.

Bioinformatics: An interdisciplinary field that develops methods and software tools for understanding biological data, especially large datasets.
Genome: The complete set of genetic material present in a cell or organism.
Sequence Alignment: A method for arranging sequences to identify regions of similarity, often indicating functional or evolutionary relationships.
High-Throughput Sequencing: Advanced technologies that allow for rapid and cost-effective sequencing of large amounts of DNA or RNA.
