100
The stage in a cell's life when it is not dividing.
What is interphase?
100
Name the three parts of the cell cycle.
What is interphase, mitosis and cytokinesis?
100
What is the genetic relationship between the parent and daughter cell in asexual reproduction?
What is identical?
100
Why was the detergent used in the DNA lab extraction?
What is to break down the lipid cell and nuclear membranes?
100
DNA is what type of "macromolecule"?
What is a nucleic acid?
200
A form of asexual reproduction that occurs in prokaryotes.
What is binary fission?
200
Describe what occurs during interphase and approximately what % of a cell's life is spent in this phase.
What is 90%? The cell grows, replicates DNA and completes normal functions during interphase; such as cellular respiration.
200
Why was the meat tenderizer used in the DNA Lab extraction?
What is to break down the proteins that the DNA wraps around?
200
A cell's chromosomes must be duplicated before mitosis occurs so that......
What is each daughter cell gets a full number of chromosomes?
300
The normal sequence of development and division of a cell.
What is the cell cycle?
300
What does the prefix cyto- mean? What is cytokineisis?
What is "cell"? The part of the cell cycle when the cytoplasm divides resulting in 2 daughter cells.
300
As you observed the slides of cell division, what stage of the cell cycle would you predict you would observe most? Why?
What is interphase? Because 90% of the time a cell is in this phase of the cell cycle.
300
What is the difference between cytokinesis in plant and animal cells?
What is during animal cell mitosis, a fiber ring contracts and divides the cell. During plant cell mitosis, a rigid cell plate forms and a cell wall is built between the two daughter cells.
400
The original cell and the cell that has been reproduced.
What is the parent and daughter cells?
400
What is mitosis? Describe the stages, in order, or mitosis.
What is the part in the cell cycle when the nucleus divides? Prophase- nuclear membrane disappears; DNA condenses in to chromosomes Metaphase- Chromosomes line up in the middle of the cell Anaphase- Chromosomes move apart to opposite ends of the cell Telophase- 2 nuclei form and the membranes are formed. The cytoplasm and cell membrane begin to pinch inward.
400
Describe 3 types of asexual reproduction. Give an example of an organism that reproduces each way.
What is binary fission- bacteria; occurs in prokaryotes and the organism splits in two budding- hydra, yeast; is a process in which an organism develops tiny buds on its body, each will form from the parent cell and be identical to the parent. Regeneration- sea star; the process of new tissue growth at the site on a wound or injury; only occurs in multicelled organisms
400
What are some samples we could use to extract DNA from? What are some samples that we could use to extract DNA?
What is anything living? What is anything non-living?
400
Why does the DNA replicates itself during interphase? What is it called when the DNA changes as it is copied during this stage?
What is so that each daughter cell has the correct and full set of genetic material? A mutation.
500
Define asexual reproduction and give 3 examples.
What is when an organism produces one or more new organisms that are identical to itself and live independently of it? What are binary fission, budding and regeneration?
500
How are cancer cells different from normal cells? Explain one way that scientists have tried to treat these abnormal cells.
What is cancer cells rapidly reproduce and go through this cell cycle creating abnormal masses of cells called tumors. Scientists try to create medications to slow the fast growing cells and interrupt the cell cycle.
500
Compare and contrast sexual and asexual reproduction.
What is both involve cell division? Asexual reproduction involves one parent, the rate of reproduction is rapid, and the offspring are identical to the parent. Sexual reproduction involves cell division and other processes, involves two parents, rate of reproduction is slower and the offspring have genetic material from both parents.
500
A single bacterium enters your body at 10 am. These bacteria reproduce at a rate of one generation every 30 minutes. How many bacteria of this type would be in your body by 8pm?
What is 2 to the 20th power or 1,048,576 bacteria!!!!!!
500
Why do you think that after a while, people who take antibiotics frequently for bacterial infections, might not find them as effective?
What is the bacteria that cause the disease gets immune to the medication. The germs or pathogens begin to change or evolve so that the medication is not as effective as it once was.
