Section 1
Explain G1
The cell is growing and carrying out normal cellular functions
How do you know a cell is in the Metaphase stage of Mitosis
The chromatids are lined up down the middle
What is apoptosis?
Programmed cell death
Characterized by memory loss, normally starts in the mid 60s due to neurons not initiating signals for cognitive function.
Alzheimer's
Explain S
DNA is copied/synthesized
Describe Cytokinesis
Two new cell are created
These are the proteins that bind to CDKs.
Cyclins
Characterized by similar features, due to a trisomy of Chromosome 21
Down's Syndrome
Explain G2
The cell copies mitochondria and chloroplasts to prepare for cell division
Come up to the board and draw Anaphase
Draw anaphase
Describe how Cancer cells take over the body.
They divide much faster than normal cells. They begin to take over the tissues, causing tissue damage, and this results in organ damage.
Leukocytes are fighting each other which causes this disease to be life threatening. There is no cure.
Leukemia
The three main stages of the cell cycle, IN ORDER
Interphase, Mitosis, Cytokinesis
Describe Telophase
Nuclear membrane returns, cleavage furrow is present, spindle disappears, the nucleolus forms
What is the checkpoint between S and G2?
To start driving protein synthesis
Describe Parkinson's Disease
Brain disorder that leads to stiffness and difficulty walking. There is no cure and it normally occurs later in life.
The space taken up by the inner contents of the cell
Volume
What are the three main points of Prophase that I pointed out during the lesson?
1. Nuclear membrane begins to disappear
2. Chromatids become visible
3. Centrioles separate and spindles form
Describe stem cells...be sure to include embryonic and adult.
Describe Huntington's Disease...How does it happen and what is a symptom?
Progressive break down of nerve cells in the brain, this can result in uncontrollable shaking and bulging eyes. There is no cure, and it is hereditary. Normally occurring between 30-40.
