Cell Cycle and Cell Division |
|
| Interphase | The phase between two M (mitosis) phase, >95% of cell cycle
G1, S and G2 |
| G1 phase | Cell is metabolically active and grows
Organelles duplicate |
| S (synthesis) phase | DNA Replication
Chromosome number remains the same, DNA amount doubles Centriole duplicates Synthesis of histone proteins |
| G2 phase | Protein synthesis for mitosis |
| M (Mitosis) phase | Equational division
Karyokinesis- Prophase, metaphase, anaphase, telophase Cytokinesis |
| Prophase | Chromosome condense
Centrosome move to opposite poles ER, Golgi bodies, nucleolus and nuclear envelope disappear |
| Metaphase | Sister chromatids visible, chromosomes are studied at this stage
Spindle fibres attached to kinetochore present at centromeres Chromosomes get aligned at the equator |
| Anaphase | Sister chromatids split and move to opposite poles |
| Telophase | Chromosomes lose their discrete identity and form clusters
Nuclear envelop develops around each cluster forming daughter nuclei Nucleolus, ER, Golgi complex reappear |
| Cytokinesis | Mitochondria, plastids, etc. get distributed in daughter cells.
In plants, wall formation starts in the middle as cell-plate. Furrow method in animal cells. |
| Syncytium | Multinucleate cell resulting from absence of cytokinesis after karyokinesis.
E.g. Multinucleate, liquid endosperm in coconut |
| Meiosis | Meiosis I and meiosis II
DNA replication only occurs once. Chromosome number is halved in daughter cells |
| Prophase I | Leptotene
Zygotene Pachytene Diplotene Diakinesis |
| Zyogotene | Pairing of homologous chromosomes
Synapsis and formation of synaptonemal complex Bivalent or tetrad chromosomes |
| Pachytene | Crossing over and recombination |
| Diplotene | Chiasmata
Can last up to years in vertebrate oocytes. |
| Anaphase I | Separation of homologous chromosomes
Sister chromatids remain attached |
| G0 (quiescent stage) | Inactive stage after G1, in cells that do not divide frequently, e.g. heart cells |
