Genome sequencing is the process of determining the complete DNA sequence of an organism's genome. This involves identifying and deciphering the order of nucleotides (A, T, C, and G) in an organism's DNA. Genome sequencing has revolutionized many areas of biological research and medicine by providing valuable information about the genetic makeup of individuals and species. This information can be used to study genetic variation, evolution, disease susceptibility, and personalized medicine. Advances in technology have made genome sequencing faster, cheaper, and more accessible, allowing researchers to sequence and analyze large genomes with increasingly higher levels of accuracy.
