Mapping the Genome

George Brown

Genomics is the study of entire genomes, which includes the entire set of genes, their nucleotide sequence and organisation, as well as their interactions within and between species. The technique of determining the locations of genes on each chromosome is known as genome mapping. The maps developed by genomic mapping are similar to the maps we use to navigate city streets. A genetic map is a diagram that shows the location of genes on a chromosome. Genetic maps use genetic markers to create a large image (akin to an interstate highway map) (similar to landmarks).
