To understand institutional racism, it is important to understand the interaction between prejudice and discrimination. Prejudice is an attitude that is based on limited information or stereotypes.
Vitamin A is involved in regulating the growth and specialization (differentiation) of virtually all cells in the human body. Vitamin A has important roles in embryonic development, organ formation during fetal development, normal immune functions, and eye development and vision.
Thus, different cells can have very different physical characteristics despite having the same genome. A cell that can differentiate into all cell types of the adult organism is known as pluripotent. Such cells are called embryonic stem cells in animals and meristematic cells in higher plants.ach cell type is defined by its particular pattern of regulated gene expression. Cell differentiation is thus a transition of a cell from one cell type to another and it involves a switch from one pattern of gene expression to another.
