a The bacterial chromosome is attached to the plasma membrane prior to DNA replication. bReplication starts and proceeds in two directions from a certain site in the bacterial chromosome. c The DNA copy becomes attached at a membrane site near the attachment site of the parent DNA molecule. d Then the two DNA molecules are moved apart by membrane growth between two attachment sites. e Lipids, proteins, and carbohydrates are built for new membrane and new wall material. Both get inserted across the cell’s midsection. f The ongoing, orderly disposition of membrane and wall material at the midsection cuts the cell in two. Fig. 19-4, p.307

Lytic Pathway Lysogenic Pathway d Accessory parts are attached to viral coat. b Host replicates viral genetic material, builds viral proteins. c Cell divides; recombinant DNA in each daughter cell. c Viral proteins self-assembleinto a coat around viral DNA. d Viral enzyme excises viral DNA from chromosome.

sporozoites sporozoites g Plasmodium zygotes develop inside the gut of female mosquitoes. They become sporozoites, which migrate to the insect’s salivary glands. a Mosquito bites human, bloodstream carries the sporozoites to liver. b Sporozoites asexually reproduce in liver cells. d Some of the merozoites enter liver, cause more malaria episodes. e Others develop into male, female gametocytes that are released intobloodstream. merozoite f Female mosquito bites, sucks blood from infected human. Gametocytes in blood enter her gut, mature into gametes, which fuse to form zygotes. c Offspring (merozoites) enter blood, invade red blood cells, reproduce asexually. They can do so often, over a prolonged period. Disease symptoms (fever, chills, shaking) get more and more severe. male gametocyte in red blood cell Fig. 20-9a, p.324
