Cell Theory
What is not apart of “Modern Cell Theory”
A) Energy flow occurs within cells
B) DNA is passed between cells during cell division
C) All cells come from pre-existing cells
D) Cells of all organisms within a similar species are mostly the same, both structurally and chemically
C) All cells cone from pre-existing cells
What is their main function medically?
To diagnose.
What are the two main ideas behind regenerative medicine?
Stem cells and tissue engineering
When did Stem Cell research first come about?
Early 1960s.
What is Forensic Science?
Where professionals take a close look at evidence from a crime scene.
When was Cell Theory initiated? And who initiated it?
In the 1830s by Theodor Schwann and Matthias Jakob Schleiden.
What is an example of a disease that radioisotopes can help identify?
Cancer, Cardiovascular Disease, Dementia
What is the objective behind tissue engineering?
to create substitutes that will fully integrate into the body, promoting regeneration and restoring lost function.
Where can stem cells be found?
What does Forensic Science use to profile DNA?
Molecular Biology
What is one of the three key point to classical cell theory?
2. All cells come from pre-existing cells
3. The cell is the basic unit of structure and organization that performs life functions.
What do the tracers release inside the body? (Allowing the organs to be studied?)
Gamma Rays
What is tissue engineering?
The development and manipulation of laboratory grown molecules, cells, tissues or organs to replace or support the function of defective or injured body parts.
What are the three types of Stem Cells?
Embryonic, Adult Stem Cells, and Induced Pluripotent Stem Cells.
1- DNA arrays
2-RNA interference
3-Cloning tools
4-Electrophoresis products
In PET, how many gamma rays are emitted?
A) 1
B) 2
C) 3
B)2
What type of stem cell produces the most amount of specialized or new stem cells?
Embryonic Stem Cells
What do forensic scientists do with samples?
They take the samples, extract DNA from the cells and copy it.
Which new radioisotopic procedure is one of the most accurate in evaluating forms of cancer?
PET- Positron Emission Tomography
What is a common focal point for researchers to regenerate tissue? And why?
Bone and joint tissues; They are known for their limited capacity for self repair.
How can stem cells help with diseases?
Stem cells can generate healthy cells to replace all diseased and affected cells.
How are the copied genetic markers separated?
Electrophoresis- process that separates ions based on their mobility
