DNA sequence database

A DNA sequence database is a digital collection that stores genetic information—specific sequences of nucleotides (the building blocks of DNA)—from various organisms. It allows scientists and researchers to access, compare, and analyze genetic data efficiently. These databases are essential for identifying genetic traits, understanding evolution, diagnosing diseases, and developing medicines. Think of it as a highly organized library where each "book" is a DNA sequence, and indexing makes it possible to quickly find and study particular genetic information across many different species or individuals.
