Parts of The Cell
What is contained in the nucleus?
DNA (genetic information)
What is the goal of cell division?
What is an embryonic stem cell?
What functions happen in the cytoplasm?
Metabolic Processes and Protein Synthesis
What is a telomere?
Sequence on the end of DNA that tells the cell how many times to replicate
What is an IPS cell?
A cell taken from an adult that is changed to act like an embryonic stem cell.
Why is the cell membrane selectively permeable?
It only lets some things in and some things out
Give an example of how a growth factor relates to cell division.
Growth factors tell cells to divide in case of injury or trauma (lots of possible examples!)
Why are stem cells important for medical research?
They allow tissue to be regenerated and implanted in other bodies; stem cells can be used all over the body
What is the difference between diffusion and facilitated diffusion?
Diffusion goes right across the membrane; facilitated diffusion goes through a protein
How does cell division lead to cancer?
If the checkpoints are ignored, the cells will divide uncontrollably
What are the two sides of the embryonic stem cell debate?
Pro - important for research
Against - consider the embryo a human life
Describe how information moves from the nucleus to the rest of the cell.
RNA takes information from the DNA and transports it from the nucleus into the cytoplasm where it creates proteins
What three questions do checkpoint proteins ask?
1.
2.
3.
Name one advantage and one disadvantage of using embryonic stem cell?
Advantage - become any cell
Disadvantage - not recognized by the immune system
