1. Molecular genetics revealed the chemical nature of the substance of heredity, showed the physicochemical prerequisites for storing information in the cell and copying it for transmission over a number of generations.
2. Modern genetics has given rise to a number of subfields: molecular, biochemical, population genetics, epigenetics, genetic engineering etc.
3. Thanks to the development of biochemical and molecular genetics, it was possible to identify the cause of various diseases that are not inherited, but associated with dysfunction of genes.
4. Mitosis is an indirect cell division, the method of reproduction of eukaryotic cells, distributing chromosomes between daughter nuclei, ensuring the formation of genetically identical daughter cells.
5. Biochemical genetics studies the mechanisms of genetic control of biochemical processes in living cells.
6. DNA repair is a special function of cells, which consists in the ability to correct chemical damage and breaks in DNA molecules damaged during normal DNA biosynthesis or as a result of exposure to physical or chemical reagents.
7. These principles served as the basis for classical genetics and were explained as a consequence of the molecular mechanisms of heredity.
8. The main processes leading to the emergence of mutations are DNA replication, impaired DNA repair, transcription and genetic recombination.
9. Genetic engineering serves to obtain the desired qualities of a mutable or genetically modified organism.
10. Genetic engineering allows to directly intervene in the genetic apparatus using the technique of molecular cloning.
11. Alleles is a different forms of the same gene, located in the same areas of homologous chromosomes, determine the direction of development of a particular trait.
12. Breeding develops methods of influencing plants and animals in order to change their hereditary qualities in the direction necessary for humans.
13. Meiosis is the division of the nucleus of a eukaryotic cell with a halving of the number of chromosomes.
