A gene is a specific section on the DNA. It is a carrier of hereditary information and, in interaction with other genes, controls the totality of bodily processes. Gene alterations can be harmless as well as cause serious malfunctions in the organism. What is a gene? Genes, as specific sections on DNA, are the basic … Gene: Structure, Function & Diseases
Can the telomeres be influenced by nutrition? Among some doctors and researchers, it is considered proven that nutrition influences the telomeres. Several studies have already been carried out on this, but some of them are controversial. A healthy diet should increase the activity of telomerase, so that the shortening of the telomeres during cell division … Can the telomeres be influenced by nutrition? | Telomeres
Definition Telomeres are part of every DNA. They are located at the ends of chromosomes and in no case code for genes. Unlike the rest of the chromosome, telomeres do not have double-stranded DNA. They are present as a single strand. In contrast to the rest of the DNA, they also do not exhibit a … Telomeres
Diseases of the telomeres Diseases of the telomeres can have serious consequences. In most cases, such subsequent effects are caused by damage to the DNA coding for proteins. Telomere disease is most often caused by a deficiency in the protein complexes (shelterins) that surround the telomeres, or in the enzyme telomerase. This promotes a disturbance … Diseases of the telomeres | Telomeres
What role do they play in the development of cancer? Telomeres can also play an essential role in the development of cancer. More often, however, the cause of cancer is a mutation within the DNA strand. However, shortening plays a role in the development of cancer as it does in aging. In the context of … What role do they play in the development of cancer? | Telomeres
Breast cancer – What does BRCA mean? Breast cancer is a disease that is usually multifactorial in origin. This means that many internal and external circumstances contribute to the coincidence of breast cancer development. Angelina Jolie is one of the best known examples where a genetic mutation increases the risk of breast cancer. She had … Breast cancer – What does BRCA mean? | Genetic test – When is it useful?
Genetic test for colorectal cancer Colorectal cancer is also favored by many influenceable internal and external influences and genetic constellations. In colorectal cancer, diet, behavior and external circumstances play a much greater role than in breast cancer. Only about 5% of all colorectal cancers can be attributed to a genetic change.If close relatives of the … Genetic test for colorectal cancer | Genetic test – When is it useful?
Determine parentage and origin Parentage is the term used to describe the range of relatives whose genetic make-up one carries. Certain genes are located at different sites in the genome and can therefore be subject to different hereditary traits. If there is a defective gene in the family history, it is possible to calculate the … Determine parentage and origin | Genetic test – When is it useful?
Cystic Fibrosis Cystic fibrosis is one of the most well-known genetic diseases and is very feared because of its consequences. The cause is merely a diseased gene, which leads to a so-called “chloride channel” (CFTR channel) being shaped incorrectly. As a result, numerous cells and organs of the body produce highly viscous secretions, which can … Cystic Fibrosis | Genetic test – When is it useful?
Can rheumatism be detected in the genetic test? Genetic diagnostics is also playing an increasingly important role in rheumatology, as increasing genetic characteristics are being researched as causative factors in certain rheumatic diseases. One of the best known genetic characteristics, which are frequently associated with rheumatic diseases, is the “HLA B-27 gene”. It is involved … Can rheumatism be detected in the genetic test? | Genetic test – When is it useful?
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 Meiosis is a special form of nuclear division and is also called maturity division. It contains two divisions, which turns a diploid mother cell into four haploid daughter cells. These daughter cells each contain a 1-chromatide chromosome and are not identical. These daughter cells are needed for sexual reproduction. Introduction In men, the germ … Meiosis
