What are the five phases of the cell cycle?
Interphase (G1,S,G2), Prophase, Metaphase, Anaphase, Telophase.
What major events are occurring during G1 phase of interphase?
Regular cell growth and maintenance.
What major events are occurring during S phase of interphase?
Genetic Material is replicated.
What major events are occurring during prophase of mitosis?
1. Chromatin condenses into chromosomes
2. Centrioles move to opposite sides of the cytoplasm.
3. Nuclear membrane and nucleolus disperse.
4. Microtubules assemble and associate with centrioles and chromatids of chromosomes.
What major events are occurring during metaphase of mitosis?
1. Spindle fibers from the centrioles attach to the centromeres of each chromosome.
2. Chromosomes align midway between the centrioles.
What major events are occurring during anaphase of mitosis?
1. Centromeres separate, and chromatids of the chromosomes separate.
2. Spindle fibers shorten and pull these new individual chromosomes toward centrioles.
3. Cytokinesis begins.
What major events are occurring during telophase of mitosis?
1. Chomosomes elongate and form chromatin threads.
2. Nuclear membranes form around each chromosome set.
3. Nucleoli Form.
4. Microtubules break down.
In what ways are the new cells (daughter cells), which result from a cell cycle, similar?
They both contain identical chromosomes (DNA).
In what ways are the new cells (daughter cells), which result from a cell cycle, different?
They differ slightly in size and number of organelles present.
What is the difference between mitosis and cytokinesis?
Mitosis involves the division of the nuclear contents while cytokinesis involves the division of the cytoplasm and cytoplasmic organelles.
A form of cell division that occurs in somatic(non-sex) cells and produces two daughter cells from an original cell.
