CLINICAL: Which diseases are caused by chromosomal aberration? Chromosomal aberrations are responsible for a large number of spontaneous abortions before birth and for many diseases. Of all of these, five diseases in particular are widespread. The best known of these is trisomy 21, better known as Down’s syndrome. These children are conspicuous for their short … CLINICAL: Which diseases are caused by chromosomal aberration? | Chromosomal aberration – What is meant by this?

What are Purines?

Purines are substances in food. They are a component of every cell and are necessary for the genetic material and the construction of new cells. When purines are broken down from food, uric acid is formed. In some people, this cannot be excreted in sufficient quantities. This results in excessive uric acid levels in the … What are Purines?

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 | 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

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

Can the telomeres be influenced by nutrition? | Telomeres

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

Mitochondria

Definition Every body cell has certain functional units, so-called cell organelles. They are the small organs of the cell and, like the large organs, have assigned areas of responsibility. Mitochondria and ribosomes belong to the cell organelles. The function of the cell organelles is different; some produce building material, others provide for order and clean … Mitochondria

What are the special features of mitochondrial inheritance? | Mitochondria

What are the special features of mitochondrial inheritance? Mitochondria are a cell compartment that is inherited maternally. All children of a mother therefore have the same mitochondrial DNA (abbreviated as mtDNA). This fact can be used in genealogical research by using mitochondrial DNA to determine, for example, the membership of a family to a people. … What are the special features of mitochondrial inheritance? | Mitochondria
