Because the flanks can be as little as 45bp, they can be added as part of a primer in a PCR reaction, so to create the above cassette, PCR amplify the ‘New sequence’ region with the flanks attached to the primers (this makes long oligos of ~65bp, but this does not effect the PCR). The un-purified PC ...

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.
