Mitosis
Meiosis
Name that stage!
DNA
Heredity
100
At this stage of Mitosis, daughter cells are pulled apart by the spindle fibers?
Anaphase
100
How many cells are produced at the end of meiosis?
4 daughter cells
100
During this stage of Meiosis, the cell divides into two diploid daughter cells.
Telophase I

What is the shape of DNA?
double helix

During this stage of Mitosis, chromosomes line up in the middle.
Metaphase
200
In what phase do cells spend most of their life?
Interphase
200
What stage of Mitosis is this?
Anaphase
200
What are the 4 letters that represent the 4 base pairs?
GCAT
200
what is the name for a different version of a gene?
allele
300
This is the first stage of Mitosis. The nucleus begins to disappear and this forms into chromosomes.
Prophase
300
In humans, how many chromosomes does each human gamete contain in meiosis?
23 chromosomes
300
In this stage of Meiosis, each chromosome lines up in the middle of the cell?
Metaphase II
300
Where is DNA found in a eukaryotic cell?
Nucleus
300
The genotype is the actual genes that an organism has, what do we call the observable traits?
phenotype
400
Mitosis has two purposes into why cells duplicate. What are they
To grow and repair tissues.
400
What is the cells produced in meiosis called. They have a single set of chromosomes.
a haploid cell
400
Which stage of Mitosis involves the cell carrying out its normal functions, growing, preparing to divide, and duplicating DNA?
Interphase
400
What is called when there is an error in a gene?
A Mutation
400
What are the chances that the offspring of a Tall pea plant (TT) and a short pea plant (tt) will be short?
0% or 0/4
500
What happens right after Telophase that involves the moving and separating of the 2 new cells?
b. Cytokinesis
500
Genetic diversity is partly a result of this phenomenon that occurs in Prophase I, where genetic material is traded amongst matching chromosomes.
Crossing over
500
What phase of mitosis is this?
Prophase
500
Why was soap required to extract the DNA from an organism (we used it in our strawberry lab)?
It dissolves the nuclear and cellular membranes
500
For some genes both alleles get expressed, what do we call genes that have this trait? for example; a red flower (CC) and and a white flower (cc) resulting in a pink flower(Cc).
co-dominance
