HYPERCELL / CELL DIVISION

BIOLOGY 1A06 ASSIGNMENT HYPERCELL CELL DIVISION EDWIN MUJICA LAB scratch # 18 LAB DAY: FRIDAY JANUARY 13, 1997 1. Where be the checkpoints in the prison cell instalment rhythm method and what be they called?         The cell division pass consists of the fostering of a pair of 2 daughter cells that atomic number 18 genetically identical. For this to occur, DNA must be duplicated and its products segregated into the nuclear spaces of the two daughter cells. The cell cycle has four phases: 1. S degree; Where chromosomes duplicate. 2. M phase: chromosome segregation sequence occurs. These two phases atomic number 18 separated by two gap phases or periods of emersion; 3. G1 phase, which occurs at the beginning of the cycle after M phase, 4. G2 phase, which occurs onward M phase. The cell Cycle processes are regulate by a series of multipurpose controls called check points. in that respect are three different checkpoint in the cell cycle: a. educate point G1, Is also called START (in yeast ) or restriction point ( in mammals). This checkpoint occurs near the peculiarity of the G1 phase. b. Checkpoint G2, which occurs at the end of G2 phase. c. Check point Metaphase, which occurs at the end of the M phase. 2. For for each one checkpoint, what conditions are monitored?         At each checkpoint, training about the billet of the cell and environment are monitored to feel whether or non the cell cycle control governing body provide continue. If cell size and the environment conditions are favorable in the G1 checkpoint (START or Restriction point), the DNA replication machinery is triggered and the control system moves forward. as intimately for the G2 checkpoint, if the size of the cell, the envi ronment conditions as well as the feature t! hat DNA replication is complete are favorable, the mitosis machinery is triggered and the cycle continues.
