Ch8 Cellular basis of Reproduction AP Bio

Ability for cells to reproduce for:

• Asexual reproduction

• Regeneration of tissue

• Growth of new tissue

Cycle of the cells life. Starts from the period of division to when it divides itself. Composed of phases where cells work towards a goal.

• Interphase

• Mitosis (division)

Mitosis is not required (ex. Red Blood Cells)

phase in which cell carries our regular activities of producing enzymes, making proteins, and surviving. Also referred to as “resting” phase.

• G1

• S

• G2

Cell carries out regular activities. Grows and collects energy for S stage.

Cell duplicates its DNA, preparing to divide later in Mitosis. DNA made into alike sister chromatids

condensed form of DNA that is duplicated and connected at the center by a centromere. Together form a chromosome.

Stage when cell duplicates its organelles and other parts to prep for mitosis.

Proteins that regulate checkpoints for regulating status of cell during the cell cycle (determines if cell is in G1, G2, etc.)

Target of the cyclin proteins. When activated, they activate necessary enzymes and proteins that put the cell into a new stage.

Division of cell into 2 identical daughter cells.

• Prophase

• *Prometaphase

• Metaphase

• Anaphase

• Telophase
