Ответ:
1. Genetics is a field of biology that studies how traits are passed from parents to their offspring
2. DNA is a molecule that is found in all organisms of bacteria, plants, animals and humans
Each of the DNA molecules in the cell nucleus consists of two chains of alternating sugars and phosphates with pairs of nitrogen bases
3. The genetic code inside DNA provides and allows instructions for protein synthesis
4. 8% of human DNA is viruses
One of the most important genetic discoveries was the fact that viruses are not only a threat to health, but also an engine of evolution. It turned out that it was they who could transfer genes from one organism to a completely different one (for example, from a plant to an animal). Therefore, in human DNA there are so many protein structures in common with viruses that have influenced our formation
5. Chimera humans exist
Of course, they do not have the body of a lion, the tail of a snake or the head of a dragon, but their genetic code is bifurcated, or rather, the cells of two genetically different people are present in their body. How is this possible? When a woman becomes pregnant with twins, and then one embryo merges with another, a chimera man is born to her. In appearance, it can be absolutely healthy, and only the development of rare diseases or incredible circumstances give out this anomaly. So, in America, a woman gave birth to 3 children, while not being their mother for DNA tests. She turned out to be a "chimera"
