5)What are the characteristics of stem cells? (Select ALL that apply)
Step by step
Solved in 2 steps
- What are some of the ethical issues that arise from using embryonic stem cells?(b) To avoid these issues, scientists use IPSCs. What are the pros and cons to using iPSCs inrelation to embryonic stem cells?Discuss the principles that govern the presence and maintenance of stem cells both in vivo and in vitro? What is the current status of the technology, and its possible applications? What are the pros and cons of the technology, and how do these issues personally affect people?Stargardt's disease was one of these that can be treated using embryonic stem cells. Why would scientist chose to use this type of stem cell in treatment of Stargard's? A. There ae not ethical issue concerning their use B. They retain stem cell properties even after specialization C. They are able to differentiate into the required cell type D. They are already specialized for this funtion
- 1.) What is one type of cell that CANNOT arise from the differentiation of a mesenchymal stem cell? A. A neuron B. A muscle cell C. An egg cell D. A bone cell 2. there is the statement: "Both stem cells and specialized cells have all the same genes. They differ in the regulation of those genes and express very different sets of genes ". Which one of the following explanations best accounts for this difference in stem cell and specialized cell gene expression? A. Stem cells and specialized cells have different activators and repressors that affect transcription B. Stem cells and specialized cells have different promoter sequences for their genes, thus affecting transcription C. Stem cells and specialized cells have different ribosomes that affect translation D. Stem cells and specialized cells use different start codons on mRNAs, thus affecting translationI 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?What are the pros and cons to Embryonic stem cells research in Medical research in this country today?
- What is differentiation? A. When a cell switches from its original purpose B. The process of multiplying the cells in the body C. The process by which cells become specialized in their form to aid in their function D. How cells grow once their place in the body has been decidedWhy are stem cells not more abundant in the human body? I learned that stem cells can proliferate into any kind of cell in the body. These cells can be very beneficial for repairing damaged tissues and replacing dead tissue. So, if stem cells have so many uses and benefits why are they not more abundant in the human body? What are the benefits and risks of an increase of stem cells? Do the benefits outweigh the possible problems? Is an increase in stem cell numbers only worth while when an injury has occurred such as in stem cell therapy? Thank youCancer can arise spontaneously, but it can also be induced as a result of environmental factors such as sun exposure, infections, and tobacco smoking. If you were asked to help allocate resources to cancer research, what emphasis would you place on research to find cancer cures, compared to that placed on education about cancer prevention?
- The term differentiation refers to (a) the loss of genes from cells. (b) the acquisition of new functional capabilities by cells. (c) the production of functionally specialized cells.
