Mitosis Chapter 9

Interphase accounts for 90% of the cell cycle

Special regions of the centromere

Bipolar attachment, attachments from both opposite regions or poles of the cell.

Cell growth, producing proteins, organelles, DNA copying, and preparation for cell division.

G1 phase(first gap), S phase(synthesis), G2 phase(second gap)

Protein production, organelle copying, growth in size

Protein synthesis, preparations for cell division

DNA is replicated which results in sister chromatids.

Interphase

Prophase, Prometaphase, Metaphase, Anaphase, Telophase

Genetic material has been duplicated but is in a chromatin form because it is uncoiled and in a uncondensed form. The centrosomes have also been duplicated and are now forming asters.

The chromatin have become chromosomes made of sister chromatids. The chromosomes are more tightly coiled with centrosomes in the center. The Nucleoli has dissapeared. The centrosomes move towards the poles of the cell.

The nuclear envelope has begun to disintegrate and the miotic spindle fibers have begun to form kinetochore connections with the chromosomes.

The mitotic spindle fibers have formed bipolar bonds and pushed the chromosomes to the center/equator of the cell. The nuclear envelope has dissapeared completely.

The chromosomes have been pulled apart by the mitotic spindle fiber and pulled equally to opposite sides of the nucleus equator.

The cell begins to form cleavage furrow and the mitotic spindle fibers begin to disintegrate and the nuclear envelope is now beginning to reform surrounding the newly created chromatin and nucleolus.

When a parent cell splits to form 2 identical daughter cells

The process of a cell duplicating its DNA or genetic material before Mitosis or cell duplication.
