BLASTN

BLASTN is a computer tool used by scientists to compare a specific DNA sequence against a large database of known sequences. It helps identify similar or matching regions, revealing possible functions or evolutionary relationships. Essentially, BLASTN quickly finds where a DNA snippet fits or is related to others in the database, making it a valuable resource for genetic research, identifying genes, or understanding biological functions. It’s like searching for a phrase in a vast library to find related texts, but for genetic information.
