Stages of the Cell Cycle
The stages of the cell cycle
What is G1, S, G2, M and G0?
The kind of cells that are produced by mitosis.
What are 2 genetically identical daughter cells?
The death of a nearby cell or the release of growth-promoting hormones.
What is external regulation?
The cell stops and tries to fix itself.
What is G0?
Two groups of proteins used in positive regulation.
What are cyclins and cyclin-dependent kinases (Cdks)?
The cell grows physically larger, copies organelles, and make the molecular building blocks.
What is G1?
The stages of Mitosis.
What is prophase, metaphase, anaphase, and telophase.
Checkpoints in the cell cycle.
What is internal regulation?
A mistake in duplication or distribution of the chromosomes.
What is an abnormal cell?
Regulates the cell cycle only when they are tightly bound to Cdks
What are cyclins?
The cell is not actively preparing to divide.
What is G0?
The step that comes after mitosis
What is cytokinesis?
Checkpoints in the cell cycle are
What are checkpoints in G1, G2/M transition and metaphase.
The checkpoints do not work and there is uncontrolled cell division.
What is cancer?
The proteins in negative regulation.
What are (Rb), p53, and p21?
The nuclear division of a cell
What is mitosis?
The mitotic spindle is broken down into its building blocks and two new nuclei form.
What is telophase?
Determines if all conditions are favorable for cell division.
That is the G1 checkpoint?
The cell gets to big.
What is an inefficient cell?
A group of tumor-suppressor proteins common in many cell
What are retinoblastoma proteins?
What is G2
The sister chromatids separate from each other and are pulled towrads the opposite ends.
What is anaphase?
The cell size and protein reserves are assessed and the replication of chromosomes is ensured.
What is the G2 checkpoint?
What is dwarfism and gigantism?
A multi-function protein that has major impact on the commitment of a cell to division because it acts when there is damaged DNA in cells.
What is p53?
