Document Summary
Protein first: tertiary and quad structure fold on themselves. Series of proteins, when fold up rna molecules will line up in grooves on the protein: nucleus will link to each other. Phototrophic = feeding on sunlight: include bacteria, algae, plants, changed chemistry of out environment, oxygen is a byproduct of their biosynthetic activity. Lithotrophic = feeding on rock: microscopic, live in deep oceans, buried in earth"s crust, inhospitable environments, some get energy from aerobic reactions (requires oxygen), but some are anaerobic. Thus bacterial cells are not completely devoid of internal organization: prokaryotes are more adaptable since they are less complex and have fewer components/functions to manage than eukaryotes. not having the dna in the nucleus makes it more vulnerable. Eukaryotes: keep dna in nucleus, plants, fungi, animals. Can"t maintain entire space making sure there is no damaged (if there is, should be able to repair) Must get nutrients inside cell if too big, too dif cult to reach.
