BIOLOGY 1A06 ASSIGNMENT HYPERCELL CELL DIVISION EDWIN MUJICA LAB persona # 18 LAB DAY: FRIDAY JANUARY 13, 1997 1. Where argon the check dots in the boothular telephone variation roll and what atomic number 18 they called? Â Â Â Â Â Â Â Â The kiosk division cycle consists of the fostering of a couple up of twain daughter cells that are genetically identical. For this to occur, desoxyribonucleic acid must(prenominal) be duplicated and its products segregated into the nuclear spaces of the two daughter cells. The cell cycle has four configurations: 1. S degree; Where chromosomes duplicate. 2. M phase: chromosome segregation sequence occurs. These two phases are separated by two gap phases or periods of increment; 3. G1 phase, which occurs at the low of the cycle after M phase, 4. G2 phase, which oc curs onward M phase. The cell Cycle processes are regulated by a series of multipurpose controls called check points. There are three diametric checkpoint in the cell cycle: a. block point G1, Is as well as called START (in yeast ) or limitation point ( in mammals). This checkpoint occurs near the barricade 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 apiece checkpoint, what conditions are monitored?
Â Â Â Â Â Â Â Â At each checkpoint, information about the posture of the cell and milieu are monitored to determine whether o! r not 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. withal for the G2 checkpoint, if the size of the cell, the milieu conditions as well as the fact that DNA replication is complete are favorable, the mitosis machinery is triggered and the cycle continues.
