The factors present in cells from birth to death are determined by the body, and other cells in the vicinity. One of the keys to the cell differentiation process is transcription factors. These hormones and chemicals direct the activities surrounding DNA, determining what gets transcribed and what is ignored. 2A. Therefore, these genes would be under-methylated. Practice problems: Epigenetics Answer Key 1. Methyl groups added to DNA or histones can prevent gene expression, so a decrease or removal of these groups will allow for activation of transcription.

Example: Nerve cell vs. All your cells have the same genes but look and act differently. Muscle cell Your muscle cells and nerve cells have the same DNA but work differently. As you grow and develop, epigenetics helps determine which function a cell will have, for example, whether it will become a heart cell, nerve cell, or skin cell. [11] [12] Three different epigenetic mechanisms have been identified: DNA methylation, histone modification, and non-coding RNA (ncRNA)-associated gene silencing. Additionally, differences in gene expression between cells, which are driven by epigenetic modifications, result in the unique function of specific cell types.

    • -how each cell knows to turn on the right genes in genome to assume correct identity involves epigenetics -every gene regulated by promoter - epigenetics involves process of turning specific genes on or off in particular cells -most common way of controlling this gene expression is by plunking a molecule (methyl group) on the promoter region.

[10] Additionally, differences in gene expression between cells, which are driven by epigenetic modifications, result in the unique function of specific cell types. Epigenetic mechanisms form a layer of control within a cell that regulates gene expression and silencing. This control varies between tissues and plays an important role in cell differentiation.

Aug 1, the epigenome is stable in somatic cells—however, that cover the basics and various key aspects of epigenetic regulation are summarized. -epigenetic processes regulate gene expression and thereby cell differentiation in the process of embryogenesis but also in the postnatal periods -also cause abnormalities in higher age -gene regulation processes can only proceed correctly if transcription occurs at right time in a defined gene locus.
