Definition Epigenetics is a broad and comprehensive biological discipline that deals with genetic functions that go beyond the mere sequencing of DNA bases. The genetic material consists primarily of DNA strands that are formed from differently arranged base pairs. In every human being there are differences in the order of the base pairs, which in … Epigenetics
Examples of epigenetics Epigenetic examples can be observed in every person in old age. Many diseases are nowadays attributed to epigenetic changes, among other things. A typical example of visible epigenetics is the so-called “X-inactivation”. Here, an X chromosome is completely silenced by epigenetic processes. This mainly affects women who have two X chromosomes. One … Examples of epigenetics | Epigenetics
What role does epigenetics play in depression? Epigenetics plays a particularly important role in the development of psychiatric diseases. The activation and inactivation of certain gene sequences can lead to diseases such as depression and schizophrenia. Age and environmental factors that lead to altered epigenetic processes are probably also responsible for this. Mental diseases are … What role does epigenetics play in depression? | Epigenetics
What’s the chymotrypsin? Chymotrypsin is an enzyme that plays a role in digestion in the human body. As an enzyme, it has the task of breaking down proteins from food and breaking them down into small components – so-called oligopeptides – which can then be absorbed in the intestines. Chymotrypsin is produced in the pancreas … Chymotrypsin – What is it for?
Where is chymotrypsin produced? The formation of chymotrypsin occurs in the pancreas, the so-called exocrine part of the pancreas. There chymotrypsin is produced in an initially inactive precursor (zymogen). This zymogen form is also called chymotrypsinogen. When chymotrypsinogen reaches the small intestine, it is then split into three different parts by the pancreatic enzyme trypsin, … Where is chymotrypsin produced? | Chymotrypsin – What is it for?
Definition – What is meant by a chromosomal mutation? The human genome, i.e. the totality of genes, is divided into chromosomes. Chromosomes are very long DNA chains that can be distinguished from each other in the metaphase of cell division. The genes are arranged on the chromosomes in a fixed order. In the case of … Chromosome mutation
What is a chromosomal aberration? Chromosomal aberration is a change in the chromosomes that is visible under the light microscope. In contrast, there are gene mutations, these changes are much smaller and can only be detected by more precise genetic diagnostics. Chromosomal aberrations can be divided into two forms. There are structural and numerical aberrations. … What is a chromosomal aberration? | Chromosome mutation
Cystic fibrosis Cystic fibrosis is a clinical picture that is caused by a mutation in a chloride channel. These channels are important for the formation of mucus in the body, as water can leak out following the chloride and thus the mucus becomes thinner. Although all organ systems are affected by this disease, the lungs … Cystic fibrosis | Chromosome mutation
Definition Chromatin is the structure in which the DNA, i.e. the genetic information, is packed. Chromatin consists on the one hand of DNA and on the other hand of various proteins. The function of chromatin is the tight packaging of the DNA. This packaging is necessary because the DNA as such would be much too … Chromatin
What are the chromatin filaments? Chromatin filaments are the structures consisting of DNA and the proteins of chromatin. The DNA as such is a very long structure. The DNA consists of building blocks that are arranged in a certain order and thus store the genetic information. As the DNA is wrapped around the histones, a … What are the chromatin filaments? | Chromatin
Definition – What are chromosomes? The genetic material of a cell is stored in the form of DNA (deoxyribonucleic acid) and its bases (adenine, thymine, guanine and cytosine). In all eukaryotic cells (animals, plants, fungi) this is present in the cell nucleus in the form of chromosomes. A chromosome consists of a single, coherent DNA … Chromosomes
What functions do the chromosomes have? The chromosome, as the organizational unit of our genetic material, serves primarily to ensure an even distribution of the duplicated genetic material to the daughter cells during cell division. For this purpose, it is worthwhile to take a closer look at the mechanisms of cell division or the cell … What functions do the chromosomes have? | Chromosomes
