Genome sequencing

Definition

Genome sequencing is the process of determining the complete DNA sequence of an organism's genome, which includes all of its genetic material. This technique allows researchers to identify the precise order of nucleotides, which are the building blocks of DNA, providing insights into genetic variation, disease mechanisms, and evolutionary relationships.
