QUESTION 16 Match the definitions and key words with the group name (programmed or stochastic). From the drop down boxes, choose the correct letter (A -- Programmed or B -- Stochastic). Celluar Aging: suggesting that the lifespan of a species is determined by an internal cellular "clock" that limits the number of cell divisions. Immune System: suggesting that aging is due to a break-down in the body's natural defense system against bacteria, viruses, and other substances. Error Theory: suggesting that errors at the cellular level produce "faulty" molecules. Evolutionary theory: suggesting that aging is a natural way to limit the reproductive potential and timespan of members of a species. Wear and Tear: suggesting that like a battery or a machine, the human…

Question 23 options: A newly discovered colon cancer cell line is established from a tumour sample derived from a patient with colon cancer. To understand more about this cell line and how it is different from normal cells, some experiments on the cell cycle of the colon cancer line are carried out. The cells are examined under the phase contrast microscope and the length of mitosis was found to be 90 minutes. Next, a DNA marker is used to find out how long DNA synthesis takes and indicates that DNA synthesis takes 3 hours. There is a gap between DNA synthesis and mitosis of 3.5 hours and a gap between mitosis and DNA synthesis of 4 hours. What is the total length of the cell cycle? _____ hours?
