Cell Division Highlights in Biology
Cell Division Highlights in Biology
  1. Prophase = longest
  2. Anaphase = Shortest
  3. Kappa particle – Paramecium (acidobacter taeniospiralis)
  4. Sigma particle – Drosophila
  5. Leptotene – Bouquet stage, Attachment plaque, beaded structure
  6. Zygotene – Synapsis, zippering, Synaptonemal complex . chromonemeta (bivalent chromosome)
  7. Pachytine – crossing over, recombination nodule, long lasting
  8. Diplotene – terminalization, chromation decondes & RNA synthesis
  9. Diakenesis – Chromosome end detach from nuclear membrane, chiasma formed.
  10. Diagenic – father ⇾ daughter ⇾ grandson
  11. Diacentric – mother ⇾ son ⇾ granddaughter
  12. Hologeneic – Mother ⇾ Daughter ⇾ Grand Daughter
  13. Holoandric – father ⇾ son ⇾ grandson
  14. Metaxenia – effect of pollen on seed coat.
  15. Xenia – effect of pollen on endosperm
  16. Cell wall removed gm (positive) ⇾ Protoplast
  17. Cell wall removed gm (negative) ⇾ Spheroblast
  18. Chlorophyll Absorb red light – Carotene
  19. Phaeoplast Absorb green light – Fucoxanthin
  20. Rhodoplast Absorb blue light – phycoerythrin
