Genome reference sequences and resequencing

In the early days of genome sequencing, little was understood about the structure of genomes and it was a very expensive exercise. The first human genome sequence, finished around the …

A primer on genome sequencing

The genome of an organism consists of one or more stretches of DNA, which can be thought of as strings of the letters A, T, G and C. A particular …
