- New treatments for several conditions are being developed using stem cells in medical waste, such as biopsy material, teeth, menstrual blood, umbilical cords, and fatty tissue removed in liposuction. For example, fat samples from injured horses are used to grow stem cells to treat tendon injuries. Explain how the two defining characteristics of stem cells enable them to be used to replace damaged or diseased tissue, so that the new tissue functions as opposed to forming a scar.arrow_forwardHeLa cells are a line of cells grown in laboratory culture that has been used extensively in research. This cell line was originally derived from malignant cervical cancer cells that were removed from a woman named Henrietta Lacks in 1951. They were grown in culture and shipped to research labs around the world where they have been used in many important experiments. Like HeLa cells, many other cell lines were originally taken from cancerous tissue. What are the advantages to using cancer cells for developing cell lines? Why not use normal tissue?arrow_forward1.) 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 translationarrow_forward
- With regard to cancer cells, which of the following are true? A. Cancer cells are clonal, meaning that they are derived from many different cells that all underwent the same clonal mutation. Cells usually accumulate many mutations over time, and this results in cancerous growth. B. Almost all cancers are caused by oncogenic viruses. no Benign tumors are dangerous because they can easily invade surrounding tissue and spread to other locations in the body. DE. Cancer cells are unable to control their division.arrow_forwardWhich of the following demonstrates the link between oncogenes and cancer? a.Oncogenes do not have mutations that increase the activity or number of molecules that stimulate mitosis. b.Oncogenes produce molecules that inhibit mitosis. c.They are genes that transform tumor cells into normal cells. d.The mutations in oncogenes increase the activity or number of molecules that stimulate mitosis, leading to irregular cell division.arrow_forwardWhich of the following would improve an individual's ability to cancer while aging?: a. decreases DNA repair accuracy during mitosisb. makes him smaller (e.g., fewer total cells)c.

- 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 functionarrow_forwardThe somatic stem cells are derived from source such as_________.a) Bone marrow, embryos, amniotic fluid and umbilical cord b) Embryos, bone, knee, foetus c) Bone marrow, fluid, umbilical cord, joint cells d) Embryo, foetus, umbilical cord, fluid.arrow_forwardThe normal function of the Rb protein is toa. act as a brake on cell division.b. produce retinoblastoma.c. facilitate retinal pigmentation.d. initiate DNA replication.arrow_forward
