Cells Slowing Dying
Label "A" is what phase of the Cell Cycle?
A-Phase
Prophase
G1-Phase
G0-Phase
Does DNA replication occur during Mitosis?
Yes, during Anaphase
Maybe
Yes, during Prophase
No, replication occurs during S-Phase
If a mutation disables a cell cycle checkpoint, what will most likely happen?
One would develop special powers
The cell will replicate slower, or stop
The cell will conduct apoptosis (programmed cell death)
Cancer may develop as cells would replicate out of control
DNA replication must occur ____________ to make sure that the daughter cells have enough DNA
after a cell divides
when a cell divides
before a cell divides
in reverse
If a DNA strand has a mutation, what will happen in later copies?
those copies will revert back to the original
it will stop functioning
they will bore holes in cells
later copied strands will also have the mutation
Mutations to DNA can be...
heredetary
caused by environmental factors
both are true
What is a carcinogen?
an environmental factor that causes a mutation that results in cancer
an environmental factor that causes a mutation
a genetic factor that results in cancer
a cancer-causing cell
Which of the following is a carcinogen?
tobacco smoke
UV light
chemical solvents
all of the above
What does uncontrolled cell division result in?
healthy, functional cells
immediate death of the cell
a mass of cells that have no visible function, called tumours
Which type of tumour can spread?
benign
malignant
Which type of tumour releases damaging hormones or enzymes to surrounding cells?
benign
malignant
Which type of tumour is non-cancerous?
benign
malignant
Metastasis is:
the ability of a tumour to self-destruct
the ability of a tumour to destroy other tissues
the non-harmful nature of a tumour
the ability of a tumour to spread
All tumours are cancerous.
true
false
A fibre-optic cable with a tiny camera that allows doctors to observe abnormal growths and take small biopsies.
X-ray
endoscopy
Ultrasound
MRI
Imaging usually used for breast tissue, bones, and lungs. The radiation released from this imaging can damage DNA.
X-ray
endoscopy
Ultrasound
MRI
Imaging that uses high frequency sound to create an image. It is often used for soft tissues, such as heart and liver.
X-ray
CT scan
Ultrasound
MRI
Imaging technique that involves multiple X-ray images from different angles; can show a cross section of tumours
Endoscopy
CT scan
Ultrasound
MRI
Imaging technique where radio waves and strong magnetic field create detailed images which a computer assembles into 3D.
Endoscopy
CT scan
Ultrasound
MRI
Physical removal of a cancerous tumour.
chemotherapy
radiation therapy
surgery
biophotonics
Technique developed at University of Toronto; light energy is aimed at cancerous tissue to identify, treat & monitor
chemotherapy
radiation therapy
surgery
biophotonics
Use of drugs to shrink tumours prior to radiation therapy; often targets unwanted tissues & causes range of side effects
chemotherapy
radiation therapy
surgery
biophotonics
Ionizing radiation is administered or implanted on a tumour, damaging the DNA and cancer cells
chemotherapy
radiation therapy
surgery
biophotonics
