Describe how Ras and p53 can alter the simplified genetic pathway controlling cell division shown below. For each of the two genes, would uncontrolled cell division result from a loss-of-function or a gain-of-function mutation?
growth factors - receptors - cyclins - cyclin-dependent kinases - cell division
What is the main difference between a stem cell and a terminally differentiated cell?
How do changes in gene expression relate to cell differentiation and specialization? Does every human cell have the same DNA, RNA or proteins?

- In other words, the master regulator initiates a program of gene expression that narrow the potential fates of the precursor's cells’ descendants to the type of cells that participate in the organ’s function. Question: Once a master regulator gene is turned on in some cells and not in others, how do cells “remember” that pattern through all the cell division that occur to form a specific organ?arrow_forwardWhat is the function of a centromere? At what stage of the cellcycle would you expect the centromere to be the most important?arrow_forwardHow does the process of cell division contribute to transmission of genetic materials from one generation to the next?arrow_forward
- How does gene expression influence the behavior of cells that contain the same genome (genetic information)? In other words, why do cells that belong to the same multicellular organism have a different structure and function?arrow_forwardHow does gene affects migrating cells?arrow_forwardWhat is the fundamental molecular difference that distinguishes a stem cell?arrow_forward
- I 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_forwardHow are molecules inherited asymmetrically during cell division?arrow_forwardA cell inherits a mutation in a gene that results in a transcription factor, called NF-kB, constantly being in its active conformation. When active, NF-kB stimulates the expression of cyclins that promote progression of the cell cycle, regardless of other conditions. As a result of this mutation, how would this cell's phenotype be affected by this mutation? A) This cell would have a cancer phenotype B) This cell would grow larger in size, but would never divide C) This cell would likely undergo apoptosis D) This cell would not duplicate its chromosomes .arrow_forward
- How do cells control gene expression? How do cell "switch" genes on/off? Draw a flow chart to match?arrow_forwardCan you draw 4th cell division of the adult stem cells. 1st and 2nd are symmetrically. 3rd and 4th are asymmetrically. What kind of cell is the product at the 4th division? Explain your reasoningarrow_forwardHow can this identical set of genetic instructions produce different types of cells?arrow_forward
