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 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
What is the normal set of chromosomes in humans? Human cells have 22 sex-independent chromosome pairs (autosomes) and two sex chromosomes (gonosomes), so a total of 46 chromosomes make up one set of chromosomes. Autosomes are usually present in pairs. The chromosomes of a pair are similar in shape and sequence of the genes and … What is the normal set of chromosomes in humans? | Chromosomes
What is a chromosomal aberration? The structural chromosomal aberration basically corresponds to the definition of chromosomal mutation (see above). If the amount of genetic material remains the same and is only distributed differently, this is called a balanced aberration. This is often done by translocation, i.e. the transfer of a chromosome segment to another chromosome. … What is a chromosomal aberration? | Chromosomes
What is a chromosome analysis? Chromosomal analysis is a cytogenetic method used to detect numerical or structural chromosomal aberrations. Such an analysis would be used, for example, in cases of immediate suspicion of a chromosomal syndrome, i.e. malformations (dysmorphies) or mental retardation (retardation), but also in infertility, regular miscarriages (abortions) and also certain types of … What is a chromosome analysis? | Chromosomes
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
Estimate the risk of thrombosis in a genetic test? The development of thrombosis is always multifactorial. Important influences on the development of thrombosis are low mobility, reduced blood flow in the veins, severe fluid deficiency and an increased tendency to thrombosis due to different blood compositions. Numerous components in the blood can be altered, which … Estimate the risk of thrombosis in a genetic test? | Genetic test – When is it useful?
Definition – What is a genetic test? Genetic tests play an increasingly important role in today’s medicine, as they can be used as diagnostic tools and for therapy planning of many diseases. In a genetic test, the genetic material of a person is analyzed to find out whether hereditary diseases or other genetic defects are … Genetic test – When is it useful?
These hereditary diseases can be determined by genetic testing Hereditary diseases can have very different mechanisms of development and can therefore be difficult to diagnose. There are so-called “monoallel” generic diseases, which are triggered 100% by a known defective gene. On the other hand, several genes in combination can cause the disease or a genetic … These hereditary diseases can be determined by genetic testing | Genetic test – When is it useful?
Implementation Anyone who wants to have a genetic test performed must first attend a genetic consultation in Germany. Here a consultation is carried out with a doctor who has been trained in human genetics or has an additional qualification. It makes sense to think about the family tree at home before the consultation. Questions about … Implementation | Genetic test – When is it useful?
