Parts of a Cell
Which cell structure produces the spindle fibers?
Centrioles
List the three main stages of Interphase IN ORDER.
G1, S, G2
When do spindle fibers first start moving chromosomes?
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
______________ is the longest stage of the cell cycle
Interphase
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?
G2
What is the name of the third phase in Mitosis?
Anaphase
A (malignant / benign) tumor is cancerous and can spread.
Malignant
Correct this statement: Mitosis is the longest phase of the cell cycle.
Interphase is the longest phase of the cell cycle.
These structures are responsible for moving chromosomes to the middle of the cell.
Spindle fibers
What happens during the G1 phase?
Cell growth
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
A jelly-like substance found inside a cell surrounding its organelles is
Cytoplasm
Approximately what percentage of a cell's life is spent in Interphase?
95%
This is the phase where spindle fibers disappear and two new nuclei form.
Telophase
Name 3 ways in which cancer can be treated.
Radiation, Chemotherapy, Surgery
What is the name of the thin barrier that encloses the cell's genetic material?
Nuclear membrane
