What is it in science, what is epigenesis?
In biology, epigenesis concerns the concept that organisms develop from cells. Organisms are made of spores and eggs that are divided in many ways. Epigenesis produces an event chain that leads to the development of the entire plant or animal. Each organism has a unique process of epigenesis, but there are common steps that must undergo all organisms. Cells use many genes all the time, and some genes of only a small amount of time are called gene expression. Epigenesis uses the gene expression as the main driving force of cell differentiation or cell changes. Since the first cells of the organism, it causes the division of cell differentiation and the expression of the gene that causes different types of cells to form.
Special cells called stem cells may turn into different types of cells depending on the environment in which the cell is. Epigenesis is initiated by stem cells that come from a fertilized egg or nebrotrus. These first cell divisions produce stem cells that will use epigenesis to convert into billionsSpecific types of cells.
Epigenesis is not just a list of instructions for a genetic program that will build an organism. The whole cell plays a role in gene expression using special methods. Methylation, adding methane molecules to genes, commonly used to suppress the gene or turn it off. The environment also plays a key role in determining gene expression, as certain properties are expressed only under certain conditions. For example, the elaboration produces more muscle cells because the lifestyle of training affects the expression of the gene.
Ancient philosopher Aristotle was the first to documented the process of epigenesis. This idea developed plants and animals, although he had no access to modern tools. At that time, most people believed that God did. Aristotle fought against this perspective and developed a surprisingly accurate model for the development process. Clearly understood that certain factors of the environment were affectedIncorrect growth process.
Modern biology has a good understanding of how organisms develop from conception. The process of gene expression and the way it causes changes has been documented and studied at the molecular level. In 1939, Conrad Waddington defined epigenesis as the development of a genetic program, which has led to many discoveries. Most surprising is that the development process is now related to many forms of cancer in humans.
