We need to screen the equivalent of 5000 molecules to ensure a 99% chance of finding gene A+. 5000 bacterial clones can be produced easily and screened quickly on one Petri dish plate. Works well ...

Genome evolution
Genome evolution is the process by which a genome changes in structure (sequence) or size over time. The study of genome evolution involves multiple fields such as structural analysis of the genome, the study of genomic parasites, gene and ancient genome duplications, polyploidy, and comparative genomics. Genome evolution is a constantly changing and evolving field due to the steadily growing number of sequenced genomes, both prokaryotic and eukaryotic, available to the scientific community and the public at large.
