Cell Cycle
The process of basic cell division
Mitosis
How many daughter cells are produced from mitosis?
2
How many daughter cells are produced from meiosis?
4
This molecule stores genetic information
DNA
The common housecat has 38 chromosomes. How many chromosomes does its haploid gametes have?
19
The cell spends 90 percent of its life in this stage of the cell cycle
Interphase
Are the daughter cells of mitosis identical or unique?
Identical
Sperm and eggs
DNA forms this x-shape when it condenses during mitosis or meiosis called ____________.
Chromosomes.
What type of asexual reproduction do bacteria normally go through?
Binary fission
This is the division of the cytoplasm
How many rounds of cell division does the cell go through in mitosis?
One
How many rounds of cell division does the cell go through in meiosis?
2
Chromatin is present during which phase of the cell cycle?
Interphase
Which stage of meiosis does crossing over take place?
Prophase 1
DNA replication happens during this stage
Synthesis
Diploid
Daughter cells of meiosis are _________________ because they have half the number of chromosomes as somatic cells.
Haploid
A DNA code for a specific trait that you inherit from your parents
Gene
Where are two places to get stem cells from?
Embryos and umbilical cord blood.
Cells divide when they get too big. Why do cells need to be so small?
So they can efficiently exchange substances (nutrients, gasses, waste, etc)
Which stage of mitosis could result in an unequal number of chromosomes in daughter cells?
Anaphase
Why is meiosis responsible for children not always looking like their parents?
Crossing over results in unique genetic combinations in each daughter cell
How are homologous chromosomes different?
They have different alleles (versions) of traits
Why do most organisms on Earth use sexual reproduction instead of asexual reproduction?
It increases genetic variety, which leads to a higher chance of survival.
