MITOSIS CYCLE EUKARYOTES

2 main phases of eukaryotes cell cycle

2 main phases of eukaryotes cell cycle

• Interphase (made up of three stages)

• M-phase: mitosis (nuclear division) and cytokinesis (division of the cytoplasm)

INTERPHASE STAGES

• First gap phase (G1)

Cell size increase and makes mRNA and proteins needed for the S phase.

• Synthesis (S)

DNA & Centrosome replicated

• Second gap phase (G2)

Nucleus well defined • Rapid cell growth and protein synthesis • The cell prepares for mitosis

MITOSIS STAGES

P-MAT

Prophase

Metaphase

Anaphase

Telaphase

Key events of PROPHASE (mitosis)

Early Phrophase

• DNA continues condensing.

• Nuclear membrane disintegrates.

• Nucleolus disintegrates.

Late Prophase

• Chromosomes appear as chromatids.

• Mitotic spindle forms.

• Centrosomes move to opposite poles.

Key events of METAPHASE (mitosis)

Metaphase - Middle

Chromosomes line up on the equator of the cell.

Key events of ANAPHASE (mitosis)

Anaphase - Away

Early anaphase:

Chromosomes separate to opposite poles.

Late Anaphase:

Non-kinetochore microtubules elongate the cell.

Key events of TELAPHASE (mitosis)

Telophase- Telephone - GIMME UR TELEPHONE NUMBER SISTER 🙋‍♀️ !!

• Nuclei reform.

• Cell elongates and furrow develops.

Cytokinesis

Cytokinesis- Cya LATER SISTER!

Two independent cells.
