1
New cards

mitosis

division of somatic cells

2
New cards

interphase

  • not a stage of mitosis

  • doubles DNA during this time

3
New cards

prophase

  • chromatids condense, become visible as pairs of chromatids

    • held together by centromere

  • spindles begin to grow from centrioles

  • nucleus breaks down

  • nucleolus disappears from view

New cards

metaphase

  • chromatid pairs line up along metaphase plate

  • spindle fibres attach to centromeres

<ul><li><p>chromatid pairs line up along metaphase plate </p></li><li><p>spindle fibres attach to centromeres </p></li></ul><p></p>
5
New cards

anaphase

  • spindle fibres attach to the chromatids to help pull them apart

  • chromatids separate as spindle fibres contract

  • chromatid = chromosome

<ul><li><p>spindle fibres attach to the chromatids to help pull them apart </p></li><li><p>chromatids separate as spindle fibres contract</p></li><li><p>chromatid = chromosome </p></li></ul><p></p>
6
New cards

telophase

  • two sets of chromosomes form clusters at poles of cell

  • chromosomes de-condense, chromatids unwind

  • new nuclear envelope reforms

  • nucleoli reform, spindles dis-assemble

7
New cards

cytokinesis

the physical separation of cells

8
New cards

non-disjunction

failure of sister chromatids to separate

9
New cards

meiosis

produces sex cells / gametes

10
New cards

meiosis 1

  • reduction division– halves number of chromosomes

  • one chromosome from each homologous pair is donated

  • 23 chromosomes (46 chromatids)

    • haploid

11
New cards

meiosis 2

  • sister chromatids pulled apart, donated to each gamete cell

  • 23 chromosomes (23 chromatids)

    • haploid

12
New cards

mitosis VS meiosis

  • mitosis // meiosis

  • all organisms (except viruses) // occurs in only plants, animals, fungi

  • creates somatic cells // creates gametes

  • 1 division // 2 divisions

  • two diploid daughter cells / 4 haploid daughter cells

  • daughter cells = genetically identical / genetically different

  • human cell with 46 chromosomes // 23 chromosomes

New cards

crossing over

  • homologous chromosomes pair up and exchange segments of genetic material
