HYPERCELL / CELL DIVISION

BIOLOGY 1A06 ASSIGNMENT HYPERCELL CELL DIVISION EDWIN MUJICA LAB SECTION # 18 LAB DAY: FRIDAY JANUARY 13, 1997 1. Where be the checkpoints in the cubicle piece pass and what be they called?         The electric carrel division oscillation consists of the boost 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 dickens daughter cells. The cell cycle per second has four phases: 1. S grade; Where chromosomes duplicate. 2. M phase: chromosome separatism sequence occurs. These dickens phases ar separated by two gap phases or periods of emergence; 3. G1 phase, which occurs at the beginning of the cycle after M phase, 4. G2 phase, which occurs in front M phase. The cell vibration processes are regulated by a series of useful tone downs called check points. There are three different checkpoint in the cell cycle: a. school point G1, Is also called gelt (in yeast ) or obstruction point ( in mammals). This checkpoint occurs underweight the peculiarity of the G1 phase. b. Checkpoint G2, which occurs at the ratiocination of G2 phase. c. Check point Metaphase, which occurs at the end of the M phase. 2. For for to each one one checkpoint, what conditions are monitored?

        At each checkpoint, information nigh the billet of the cell and surround are monitored to determine whether or non the cell cycle control system can continue. If cell size and the purlieu conditions are favorable in the G1 checkpoint (START or Restriction point), the DNA getting even machinery is triggered and the control system moves forward. as well for the G2 checkpoint, if the size of the cell, the environment conditions as well as the feature that DNA counterpunch is complete are favorable, the mitosis machinery is triggered and the cycle continues.
