will placing an inhibitor in EB cell with a particular differentiation cell in viro creat an directs a completely uniform and singular differentiation of cells
Homework Answers
Embryonic Stem cells reduce the number of murine cells in the culture of EB cells.
EBs are dissociated and cells are cultured as a monolayer forming Differentiated Embryonic cells. This allows for initial differentiation of the human ES cells as aggregates and further differentiation as a monolayer wherein cells can be exposed to exogenous growth factors.

identify one gene (other than myosin heavy chain) that is upregulated during C2C12 cell differentiation. Describe the experimental evidence supporting an increased expression of this gene during differentiation. What is the purpose of this gene and how does it make C2C12 cells more specialized? Explain.

Which of the following statements is TRUE about X inactivation? A. Inactivation of a particular X chromosome depends on its genetic content. Inactivated X chromosomes are in some way "marked" such that all clonally related cells (daughter cells) have the same X chromosome inactivated. B. Inactivation of an X chromosome occurs at random early in embryonic development. Inactivated X chromosomes are in some way "marked" such that all clonally related cells (daughter cells) have the same X chromosome inactivated. C....

What best describes whether a virus is likely to infect a particular cell? Group of answer choices (A) Viruses infect the first cells they encounter. (B) A virus will only infect host cells with the correct surface receptors. (C) If a host cell is weakened, viruses are likely to infect it. (D) The initial choice is random but once a cell type is chosen it becomes the preferred host.

Topic 3. Tell the "T cell story". In particular, where are they born? Where do they receive their education? What are the two criteria for "graduation"? When do they stop being naïve mature T cells? What two things must happen for a T cell to become "activated"? Which type of activated cell participates in humoral immunity? What does the other type of activated T cell participate in?

Drosopholia eye development is an example of cell differentiation directed by signal binding to a receptor tyrosine kinase (RTK). In this pathway, R7 photoreceptor development requires a receptor (SEV, sevenless), which is activated by binding to a plasma membrane bound signal (BOSS, bride-of-sevenless) displayed on the adjacent R8 cell Receptor activation leads to activation of RAS via two proteins, Drk (down- stream of receptor kinases) and Sos (son-of-sevenless). Activated RAS leads to activation of a phosphorylation cascade that activates the...

2) The amount of DNA per cell of a particular species is measured in cells found at various stages of meiosis and the following amounts are obtained: 3.7 pg, 7.3 pg, 14.6 pg Match the amounts of DNA above with the corresponding stages of the cell cycle. You may use more than one stage for each amount of DNA. A. G1 B. Prophase I C. G2 D. Following telophase II and cytokinesis E. Anaphase I F. Metaphase II
