New cards

Interphase

  • Cell growth

  • 90% of cell cycle

  • 3 Phases:
    g1 - growth for newly formed cell

s - synthesis of new dna

g2 - prep for mitosis

2
New cards

Prophase

  • 1st phase

  • Centrioles grow spindle fibersthat extend into nucleus and attached to centromere

New cards

Metaphase

  • 2nd phase

  • Chromosomes move toward the middle of the cell

  • Centrioles move to end of cell

New cards

Anaphase

  • 3rd phase

  • Centromeres dissolve and chromosomes move towards the centriole guided by the spindle fibers

New cards

Telophase

  • 4th phase

  • Chromasomes reach opposite poles of cell

  • Spindle fibers dissolve

  • Membrane begins to form around each mass of chromosome

  • (cytokenisis at the end, organelles divide into each cell)

6
New cards

Meiosis

  • Cell division by which gametes with half the number of chromosomes are produced (2n → n)

  • Gametes (M,F) combine to form zygote, ensures genetic differences

7
New cards

Interphase I (meiosis)

Chromosomes replicate instead of DNA

Each Chromosomes consists of two sister chromatids

8
New cards

Prophase I (meiosis)

  • synapsis occours: homologous chromosomes come together to form a tetrad

  • tetrads are two chromosomes

  • crossing over occurs

9
New cards

Metaphase I (meiosis)

  • Tetrads align on the metaphase plate

  • Orientation of pairs is random = variation occurs

10
New cards

anaphase I (meiosis)

  • homologus chromosomes go towards opposite poles

  • sister chromatrids remain attacged at centromere

11
New cards

telophase I (meiosis)

  • each pole now has haploid set of chromosomes

  • Cytokenisis occurs and 2 cells are formed


goes onto pmat II which isthe same as mitosis
