What is Genome Sequencing?
Genome sequencing is the process of determining the complete DNA sequence of an organism’s genome. It involves identifying the order of nucleotides (Adenine, Thymine, Cytosine, and Guanine) in an organism’s DNA. This technology has revolutionized fields such as genetics, medicine, and biology by providing insights into an organism’s genetic makeup, variations, and potential genetic predispositions to diseases.
Long answer
Genome sequencing refers to the determination of the precise sequence of nucleotides in an organism’s DNA. The human genome consists of over 3 billion base pairs organized into 23 pairs of chromosomes. Genome sequencing helps scientists understand the genetic blueprint that influences an organism’s traits, behaviors, and susceptibility to diseases.
