PPT-V9: Cellular differentiation - Epigenetics

In developmental biology cellular differentiation is the process where a cell changes from one cell type to another Most commonly the cell changes to a more specialized type Differentiation . Sex Differentiation and Dimorphism occurs during……. I. n utero. Development. Adulthood. This differentiation and dimorphism arises from circulation of sex steroids . Testosterone, Estrogen, Progesterone, 5ɑDHT. Kevin Ferriter. Mariah Minder. From Yesterday…. Do you think your brain cell and your blood cell have the same DNA sequence?. Genetics. Every cell contains all of your DNA. Not every cell expresses all of your DNA. -What is epigenetics? -Epigenetics and us -Past, present, and future You Are What Your Mother Ate:What is Epigenetics?Daniel Lieber DNA is the Source of Heritable Information in the Cell organism Crea Part Two.

There are hundreds of different types of cells in your body, and each type has a unique function. We’re going to compare some different types of cells to see how much they have in common. . Epigenetics comprises (hereditary) changes in gene expression without altering the DNA sequence . Epigenetics is a biological subdiscipline that deals with questions of development, heredity, gene regulation and evolution . .
