The Cell Cycle
What are the 5 stages of the cell cycle?
G1, S, G2, Mitosis, Cytokinesis
The phase in mitosis where the chromosomes align along the center of the cell
Metaphase
True or False - Meiosis follows PMAT
TRUE!
Side effect of TOO much cell division (mitosis)
Cancer
What is the function (job) of the mitochondria?
undergoes cellular respiration: uses glucose and oxygen to generate ATP for essential body processes
What occurs during mitosis?
2 daughter cells are created from an original parent cell
The phase in mitosis where the genetically identical chromosomes move to the opposite poles of the cell
Anaphase
In what part of the meiosis cycle does the "cross over event" occur?
prophase 1 - metaphase 1
If a person gets a paper cut and mitosis does not occur at the wound site - what will happen?
The person will continue to bleed from that location (open wound)
What are the monomers of Nucleic Acids?
Nucleotides
What occurs during the S phase of the cell cycle?
DNA replication
The phase in mitosis where the parent cell officially splits into two identical daughter cells
cytokinesis
Will the process of meiosis generate diploid or haploid cells?
Haploid
What can happen if a sperm fertilizes an egg AND a polar body ?
TWINS
What process is this:
CO2 + H2O + sunlight > Glucose + O2
photosynthesis
What occurs during the G1 phase of the cell cycle?
The phase in mitosis where the chromosomes condense
Prophase
If a parent cell has 24 chromosomes, how many chromosomes are present in its daughter cells following meiosis 1 and 2?
12 chromosomes (half)
Which of the following processes is most closely related to "infertility"?: cell cycle, cancer, meiosis, mitosis
meiosis - production of viable gametes
Name a type of protein in the cell membrane
transport , channel , peripheral, transmembrane, gated, enzyme, receptor
If a parent cell has 22 chromosomes, how many chromosomes are present in its daughter cells following mitosis/cytokinesis?
22 chromosomes (identical)
The phase in mitosis where the chromosomes DEcondense
Telophase
The phase in-between Meiosis 1 and 2
Interkinesis
Sometimes during meiosis, an extra chromatid is present on the 21st chromosome. What is the name of this genetic condition?
Down Syndrome - Trisomy 21
What is missing from this formula:
Glucose + O2 > ATP + CO2 + _____
H2O (water)
