WebThese immune system cells have many lysosomes for the destruction of bacteria and other invaders brought into the cell via phagocytosis. The enzymes (hydrolases) that carry out this catabolic activity are synthesized in the endoplasmic reticulum, modified in the Golgi, and transported to the lysosomes. Part A Web© 2012 Pearson Education, Inc. The genome of a prokaryote typically – has about one-thousandth as much DNA as a eukaryotic genome and – is one long, circular chromosome packed into a distinct region of the cell. Many prokaryotes also have additional small, circular DNA molecules called plasmids, which replicate independently of the chromosome.
