How does expression of alpha and beta TCR transgenes alter thymocyte development?
Answer:- expression of alpha and beta TCR ( T cell receptor)
transgenes alter thymocyte development by following
mechanism:-
- CD4- and CD8- thymocytes expressing a TCR alpha chain have
decreased
capacity to give rise to CD4+ CD8+thymocytes when compared with
wild‐type thymocytes. This incomplete CD4–CD8– to CD4+ and CD8+
maturation is mediated by the transgenic TCR alpha chain pairing
with endogenous TCR beta chain but not with endogenous TCR gamma
chain.

How does differential gene expression control organismal development? All cells are differentiated early in development, and that determines the final fate of the cell. Epigenetic inheritance controls what genetic material ends up in each individual cell, determining its fate. Each cell contains different genes that are controlled by gene regulators and determine the final fate of the cell. Development is controlled by genes regulated in different ways in different cells and at different times during development.
Aberzombie, Inc. has 2 divisions, Alpha and Beta. Beta produces a unit that sells for $50, with the following costs based on its capacity of 250,000 units: Direct Materials $15 Direct Labor $12.50 Variable OH $2.50 Fixed OH $7.50 At present Beta does not sell any units to Alpha. Beta is selling 150,000 units externally, and Alpha is purchasing 75,000 units from an outside supplier for $45 per unit. A.) What happens to Beta's income if it meets the outside...

How to find Moseley's parameters for K-alpha, K-beta, L-alpha, and L-beta X-Ray Fluorescence? Could you explain explicitly? If you find them online, please cite the webpage. Thank you!
Alpha and Beta are the only firms selling gyros in the upscale town of Delphi. Each firm must decide on whether to offer a discount to students to compete for customers. If one firm offers a discount but the other does not, then the firm that offers the discount will increase its profit. The figure shows the payoff matrix for this game. What is the Nash equilibrium in this game? A. There is no Nash equilibrium. B. Alpha offers a...
