What is Genome Sequencing?

A genome is the complete DNA content of an organism. DNA carries genetic information that guides the development and function of living creatures. DNA is composed of four nucleotide bases (A, T, C, and G), which are arranged into groups known as genes. Each gene contains hundreds
of nucleotide bases. The exact order of the nucleotide bases in the gene is called a sequence. The sequence will determine what protein that gene makes. These proteins are needed to carry out biological functions in all
organisms.

For example, in salmon different genes regulate temperature, growth, and disease resistance. Understanding when, why, and how each of these genes works provides information about salmon that could be used in further research.

In order to sequence a genome, scientists must figure out the exact order of the nucleotide bases in the DNA of an organism. The process is mostly done by machines, with scientists interpreting the sequence found. The results show the location of genes within the genome, as well as the nucleotide bases
that make up these genes, the areas of DNA that turn genes on and off, and the long sections of DNA that separate genes from each other. By sequencing the genome, scientists get a map of the organism's DNA. By identifying the genes in a genome, researchers can get hints as to what each gene does and how it works in that organism.
