Plasmid(质粒) More Info: http://en.wikipedia.org/wiki/Plasmid Extra-chromosomal DNA molecule Able to replicate independently of the chromosomal(染色质)DNA Usually circular and double-stranded
Plasmid High efficiency of promoter Ori (Origin of Replication) MCS (Multiple Cloning Site) Selective marker
Eukaryotes(真核生物)& Prokaryotes(原核生物) • Chromosome • Nuclear membrane • More complicated to deal with From: http://www.windows.ucar.edu/earth/Life/images/celltypes.gif
Gene regulation (ex. Operon) • RNA polymerase • Promoter • Operator • Repressor • Inducer: ex. IPTG • In an operon, several genes are controlled by one promoter • Example: lac operonin E.coli • Video (http://www.youtube.com/watch?v=oBwtxdI1zvk)
