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
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 is a Wolf-Hirschhorn Syndrome? The Wolf-Hirschhorn syndrome describes a complex of different malformations, which are caused by a change in the chromosomes (chromosomal aberration). The malformations include above all changes in the head, brain and heart. The Wolf-Hirschhorn syndrome occurs in about 1:50. 000 children. It affects girls more frequently than boys … Wolf-Hirschhorn Syndrome
TreatmentTherapy The Wolf-Hirschhorn-Syndrome is not curable. A purely symptomatic therapy is carried out with the aim of improving the quality of life of those affected. This includes various forms of therapy such as occupational therapy, physiotherapy, speech therapy and surgical correction of some malformations. Epilepsy should also be treated with medication. In some cases, artificial … TreatmentTherapy | Wolf-Hirschhorn Syndrome
