Eukaryotic Cell Cycle, Mitosis & Meiosis - Coggle Diagram
Eukaryotic Cell Cycle, Mitosis & Meiosis
5 phases of Mitosis
Metaphase
chromosomes are aligned in a single row
Anaphase
sister chromatids separate from each other and move to opposite poles
Prometaphase
Mitotic spindle is fully formed
Prophase
chromosomes condense & nuclear envelope begins to dissociate
Telophase
chromosomes decondense & nuclear envelope re-forms
4 cell cycle phases
S phase
Chromosomes replicate
G2 phase
Cell synthesizes proteins
G1 phase
Cell growth occurs
M phase
Mitosis and cytokinesis
Variations
Submetacentric
Acrocentric
Metacentric
Telocentric
Mitotic Cell Division
produce two new cells (the daughter cells)
Mitotic spindle
Composed of microtubules
types of microtubules
Astral microtubules
Polar microtubules
Kinetochore microtubules
2 divisions of Meiosis
Meiosis I
Metaphase I
metaphase plate as double row
Anaphase I
segregation of homologs occurs
Prometaphase II
each pair of sister chromatids is attached to
single pole
Telophase I & Cytokinesis
2 daughter cells are separated
by a cleavage furrow
Prophase I
Meiosis II
Metaphase II
Anaphase II
Prometaphase II
Telophase II & Cytokinesis
Cleavage furrows separate the 2 cells into 4 cells
Prophase II
Chromosomal mutations
Duplications
Inversions
Translocation
Deletions
