Crescentus* - **ParB** first binds to the **ParS** site (located within the DNA, near the origin of replication) forming the partioning complex - This complex forms at two opposing points within the chromosome - One end attached to a **stalk protein** (which can be used to attach to solid surfaces) - The other attaches to the polymeric **ParA** complex which begins elongated and is shortened over the course of replicated, pulling the replicated DNA with it in the process This same system is used in almost 70% of 400 sequenced bacterial genomes, however alternative systems have been discovered. ### Budding just a couple of fun guys (see what I did there haha ha….) ### Filamentous hair like
