There are two basic types of cell in the living world: the cells found in bacteria (prokaryotes), and the cells found in plants and animals (eukaryotes). They have characteristic differences in their structures and behaviour. Prokaryotes have a circular DNA molecule consisting mainly of genes; they multiply by dividing (!) to give identical daughter cells; their protein-making machinery (ribosomes) are of a particular size; their outer membranes have a particular structure; and they are much smaller. Eukaryotes have linear DNA molecules in pairs (chromosomes); the genes come with lots of “junk...
