Parts of a Cell
Which cell structure assembles the mitotic spindle?
Centrosome
List the three main stages of Interphase IN ORDER.
G1, S, G2
When do chromosomes line up in the middle of the cell forming an imaginary plate?
Metaphase
TRUE or FALSE: Cancer cells go through apoptosis and die to prevent spreading.
FALSE: Cancer cells do not go through apoptosis.
The __________________ is the region of a chromosome where spindle fibers attach.
Centromere
Chromosomes are made up of two identical sister ______________________
Chromatids
When do the chromatids replicate during interphase?
In which stage are chromosomes separated and moved to opposite poles?
Anaphase
What are two different things that can cause cancer?
Exposure to UV light, smoking/vaping, radiation, toxins, etc
Correct this statement: Mitosis is the division of the cytoplasm and cytokinesis is the division of genetic material.
Mitosis is the division of genetic material and cytokinesis is the division of the cytoplasm.
Contains the genetic material and serves as the control center of the cell.
Nucleus
During which stage of Interphase does the cell check itself for errors before dividing?
G2
In what two stages do you see nuclear envelopes?
Prophase & Telophase
A (malignant / benign) tumor is cancerous and can spread.
Malignant
The term referring to DNA and protein.
chromatin
These structures are responsible for moving chromosomes to the middle of the cell and shorten when chromosomes are pulled apart.
Spindle fibers
What happens during the G1 phase and what stage does a cell enter if not dividing?
Cell growth & G0
What is the end result of the cell cycle?
2 daughter cells with identical sets of chromosomes
Explain how a cancerous cell is different from a non-cancerous cell.
Cancerous cells grow and divide uncontrollably, potentially causing tumors to form and spread. Normal cells follow signals given by the body to grow & divide, and remain in an organized formation.
A continuous thread of DNA is called a...
Chromosome/Chromatid
Where spindle fibers attach to the centromere and motor proteins are located.
Kinetochore
Approximately what percentage of a cell's life is spent in Interphase?
90%
The difference between animal and plant cell cytokinesis.
Plant cell - cell plate forms before cytoplasm divides
Name 3 ways in which cancer can be treated.
Radiation, Chemotherapy, Surgery
The site where bacterial genetic material is prepared for division.
Origin of replication
