Which of the following statements did Yamanaka rely on to produce induced pluripotent stem cells (IPSC)? [Note: This is higher level thinking. All statements on their own are
correct and may be related to IPSC production but there is only one statement that played an essential role in the production of IPSC)
O A. A proportion of embryonic stem cells can differentiate into adult stem cells.
B. Only a small proportion of genes are expressed in each celI.
C. Telomerase is active in pluripotent stem cells.
D. All genes retain the potential to be expressed.
How does gene activation lead to cell differentiation? Explain the correct answer and explain why the others are wrong.
A. Different genes are activated in different cells, causing each cell to have a unique funcation
B. The same genes are actives in every cell of your body, causing every cell to function the same
C. Certain cells only have parts of DNA that causes cell deferentiation
D. Unique genes are in different cells, causing each cell to have a unique function
Cellular reprogramming and induced pluripotent stem cells have allowed scientists to model various diseases and screen drugs in these in vitro models. Please select a disease (like cancer) that can be modeled through the generation of induced pluripotent stem cells. You can use published literature and explain:1) why is it important to model such a disease?2) what were the key findings after modeling such a disease? 3) a drug that has been screened in this disease model. Explain in detail the main findings.

Which of the following would be a true statement to tell them? a) 100% of their male offspring will likely be carriers of the recessive allele that causes the disease b) 75% of their female offspring will likely be carriers of the recessive allele that causes the disease c) 100% of their male offspring will likely…arrow_forwardWhat are the main characteristics of genetically encoded calcium indicators: (can be more then one answer) A.Always allow ratiomeric measurement of calcium signal.B.Can be modified by genetic engineering, allowing to change their property, such as fluorescence wavelength, sensitivity, etc.).C.Much less sensitive than chemical indicators.D.Must be transfected, unlike chemical indicators that must be injected or penetrated through the membrane.arrow_forward
- What is an induced pluripotent stem cell? a. A cell from which the nucleus has been removed b. A cell extracted from an early embryo c. A specially treated somatic cell that can develop into any cell type d. A specially treated embryonic stem cell that develops into one specialized cell typearrow_forwardP53 is a tumor suppressors protein. The protein is present in the cell at all times but is activated by protein kinases that are, in turned activated by DNA damage. A mutation of the P 53 gene in cell results in a form of P53 that is permanently active. What would happen to the mutant version of the P53 gene? Group of answer choices A. it would spread to neighboring cells but not very far B. it would be found in tumor cells only C. it would take over the world and make us all do its bidding D. it would only be found in the original cell in which the mutation occurred E. it would spread to all cells in the bodyarrow_forwardI am confused about how stem cell transplants works. If you put a semi differentiated tadpole nucleus in a denucleated egg cell, it’ll develop into a fully formed tadpole, but if you put a fully differentiated tadpole nucleus, it won’t (because the genes have already been expressed in a way where the cytoplasmic determinants cannot operate to the fullest). Then how come in stem cell transplants, you use adult nucleuses that are already developed and transplant them into the denucleated egg cells?arrow_forward
