A human genome contains over 3 billion base pairs. Now, if a scientist wants to identify similar portions of DNA in a human genome to a chimpanzee genome, which is also over 3 billion base pairs long, the scientist would need to use a computer program. This is where CoGe comes in. CoGe | A human genome contains over 3 billion base pairs.
