Step by step
Solved in 3 steps
- If you were to design an experiment to get p53 back into cancer cells, how would you go about that work? How would you direct p53 into the nucleus of cancer cells without directing it to the nucleus of healthy cells? As an overabundance of p53 in healthy cells would cause problems. Could someone in depth answer these questions for me and explain them cellularly.All the cells of one organism share the same genome. However, during development, some cells develop into skin cells while others develop into muscle cells. Briefly explain how the same genetic instructions can result in two different cell types in the same organism.What percentage of the human genome is nowpredicted to have functionality in at least one cell type?

- In a few sentences, describe how p53 guards the genome. Include at least two specific ways that p53 guards the genome. In a few more sentences, describe the structure and function of the p53 protein. Structure: what domains are present in the p53 protein? Do p53 work as a single protein or as part of a complex? Function: what do the different domains do? How can p53 do so many different things?A cultured mouse cell line has a mutation in a gene encoding a ribosomal protein. The mutant protein impairs the fidelity of translation such that incorrect amino acids are incorporated at higher rates than normal during protein synthesis. It also slows the rate of mRNA translation and increases the duration of the cell cycle, i.e., the mutant cells grow and divide more slowly. Researchers noted that these cells express higher levels of chaperone proteins than normal cells. Which of the following is the most likely explanation for the elevated chaperone levels.Which of the following is true about epigenetic modifications? -Epigenetic modifications always repress transcription -Epigenetic modifications are irreversible -Epigenetic modifications only occur on the tails of histone proteins -Epigenetic modifications influence the relationship between DNA and histone proteins
