Document Summary
Note: the number prior to the information describes a certain point in the lecture slides the lecturer addresses. Food production i. e. pasteurization, as bacteria can grow rapidly in food. Biotechnology: we want to harness microbes to grow certain factors such as hormones i. e. insulin. Fighting disease: understanding how microbes grow in us to learn how to fight infection better i. e. antibiotics. Slide 3: chromosomes once duplicated will separate. This separation is dependent on membranes: time varies between species to species. It replicates very rapidly in lab conditions but much more slowly in the human gut (lots of competition) Slide 4: many bacterial cells divide by binary fission. This is where the cell divides into two cells by first elongating to double its size and forming a partition in the middle called the septum. This is due to an inward growth of the cytoplasm, membrane and cell wall. Eventually this septation fuses with itself to give you two daughter cells.
