DNA chain – Ladders with millions rungs

DNA chain – ladders with millions rungs – DNA strands looks like spiral ladders
with the millions rungs, each of which carries the instructions written by chemical code.
If we could unravel and stretch the DNA of a single human cell, measure the approx.
2 meters, its thickness, however, would amount to approx. 0.000002 mm. Chain DNA from
the body of one man is 16 times longer than the path from Earth to the Moon.

DNA types – Distinction between two types of DNA

DNA types - Mitochondrial DNA

DNA types – Distinction between two types of DNA

DNA types – Distinction is made between two types of DNA:

  • Nuclear DNA, in the nucleus of each cell of the human body consists of 20-25 thousand. genes. After the death of its host quickly degrades.
  • Mitochondrial DNA (mtDNA), contains only 37 genes. During the study, scientists use mtDNA, which is inherited only from the mother, it retains a relatively high resistance to the influence of sexual selection, however, it is a frequent mutations.

Human body bacteria – Digestive tract microorganisms

Human body bacteria – Weight of digestive tract microorganisms

Human body bacteria – Weight of digestive tract microorganisms – The total weight of bacteria
living
in the human digestive system is approx.
1.5 kg. In the large intestine,
we have
100 trillion microorganisms. 10 times more than the number of all cells in the body.
They are divided into
roughly 400 species.

Studies have shown that it is the changes in the number and species of bacteria in the gut
have a negative impact
on the psyche of the patients. According to specialists bacterial flora
may be responsible
not only prone to depression, but depression symptoms in themselves.

At one cm square elbow stays on average 10 thousand. bacteria 113 different species,
but more than
90% are 10 of them. The least bacteria on human skin found between the toes,
the largest
habitat of the navel.

Old age mental activity – Number of neurons

Old age mental activity - Brain weight with age

Old age mental activity – number of neurons

Old age mental activity – number of neuronsThe decrease in mental activity in old age
was attributed to the decreasing with age, the number of brain cells.
Neurologists from universities in Boston and Washington, however, proved.
That almost
all of the 10 billion cells used while thinking, they are active even in 80-year-olds.

Alcoholism effects – Repairing damaged neurons

Alcoholism effects - Alcoholic on street in Spain

Alcoholism effects – Repairing damaged neurons

Alcoholism effects – repairing damaged neurons – Scientists from Wurzburg in Germany
found that
damage to brain cells caused by excessive alcohol consumption can be repaired only partially.

They note that
in the interest of alcoholics is the fastest return to sobriety. Longer heavy drinking
causes
brain regeneration proceeds with great difficulty.

Yeast milk – Longing for the taste of cow’s milk

Yeast milk – Longing for the taste of cow’s milk

Yeast milk – Longing for the taste of cow’s milk, but professing an orthodox vegan scientists from the US. Solved their problem by introducing into yeast cells cow genes for the synthesis of milk components. In a similar way is prepared for quite a time certain medications. The milk milked from yeast has a chance to appear in stores in two years.
