How many cellular divisions are there in Meiosis?
TWO
Name the stage of mitosis seen here:
Telophase
This is the amount of haploid cells created at the end of Meiosis.
FOUR
What is the cell division process where cells replace other cells with genetically identical copies?
Mitosis
In what kind of cells does Mitosis happen?
Somatic (body) cells
Cancer, generally, can be treated in 3 different ways. Name TWO of them.
2. Radiation (radio-therapy)
3. Chemo-therapy
This is the first stage of the cell cycle in which the cell grows.
G1
This part of the cell cycle is when the cell makes copies of its DNA.
S Phase
In humans, what is the # of chromosomes in our somatic cells at the end of mitosis?
46
In humans, this is our haploid # of chromosomes
23
In this part of the cell cycle extra organelles are produced inside the cell and the cell is preparing for mitosis.
G2 phase
Sister Chromatids, containing different DNA, move to the middle of the two dividing cells during this stage. (be specific!)
Metaphase II
In which cellular division process do we end up with haploid cells.
Meiosis
Which cellular division process ends with two diploid cells?
Mitosis
In what kind of cells does meiosis happen?
Gametes
What are the thread-like structures inside the nucleus of the cell that hold all of your genetic information (DNA)?
Chromosomes
The G1, S, and G2 phases together are collectively known as this.
Interphase
In class, we discussed a few different causes of cancer. Name ONE of them.
Epigenetics
Toxins from pollution or smoking.
Drug use.
Radiation overexposure.
Inadequate nutrient intake.
Genetics
Mutations to DNA.
Have to be inherited via gametes.
What is the process by which some organisms do not need a partner and give rise to genetically identical offspring?
Asexual reproduction
What is the name for a collection of cells that are growing abnormally? (Hint - it can be benign or malignant)
Tumor
What is the name of the process in which sections of maternal and paternal homologous chromosomes exchange genetic information to create genetic variation in new chromosomes?
Crossing Over
Crossing over occurs in what phase of Meiosis?
Prophase I
What is the name for the part of the cell cycle where the jelly-like fluid inside of the cell divides and creates 2 new daughter cells?
Cytokinesis
If the cell detects that the DNA is damaged a little bit at the first checkpoint, it will stay in a secondary growth phase. What is the name of this phase?
G0
What is the name for a pair of chromosomes in a cell that contain the same genes in the same order?
Homologous chromosomes
When a haploid egg and a haploid sperm unite through fertilization, what is the name of the first diploid cell that is created as a result?
Zygote
When two gametes meet, what is name for the chance occurrence that results in genetic variance (diversity) among offspring?
Random Fertilization
What is the term for when cancer cells enter the bloodstream and can travel to other parts of the body?
Metastasis
What is the name for the different versions of the gene for each trait carried on a chromosome? (Hint - You get one of these from each parent)
Alleles
If the cell’s DNA is damaged a lot, then all the lysosomes burst in a process called this...
Apoptosis
