The utility of a reference genome

In the 18 years since the completion of the Human Genome Project, the practicality of assembling full genomes for a wide range of taxa beyond ourselves has only improved. While model taxa systems have achieved genomes before many others, it is now possible for whole genomes to be assembled for a range of non-model organisms as well. But how do we assemble the genome of a species for the very first time (often de novo – literally “from the new”)? What can we do with this genome? Why is it so useful? Let’s delve into the process and outcomes of genome assembly a little more.
