Nucleic acids are isolated and analyzed from different cells in a mammal. How would the DNA sequence of a skin cell be different from the DNA of a nerve cell? How would the RNA isolated from a skin cell and a nerve cell be different? A stem cell is a cell that is not currently differentiated into a specific cell type but that retains the capacity to differentiate into different cell types (such as nerve and skin). How does the existence of stem cells help verify your answer to the preceding questions?
