Heteropyknosis Positive

Scientists from America reported the positive properties of heteropyknosis - changes in chromosomal structure and color in cells. The cause of heteropyknosis may be a specific genome mutation, formed due to some external influence or somehow inherited from a parent. The development of heteropyknosis cannot be monitored in laboratory conditions, but it is present in any living cell. This implies its importance in the development of new body cells. If we look at the history of the study of heteropyknosis, its description was first described back in 1954. At that time, Professor Gaylor spoke of the presence of small fragments located on the chromosome map, which emphasized a special role in cell division. Subsequent more extensive studies confirmed the assumption - the study of chromosomes confirmed the presence of specific areas that are involved in maintaining the healthy functioning of the cell. Malicious cells can be localized inside the nucleus or near it. As a rule, the lesions are green on the outside and blue on the inside. Scientists believe that such pictures on tissue can show the extraordinary properties and structure of chromosomes in a given organ. It is worth noting that DNA can accumulate from place to place. However, it is not known whether they carry the same information or differ from each other. The assumption is confirmed by experiments conducted on rabbits. Scientists have identified a significant change in one of the genes responsible for cell division.

**Positive heteropyknosis** - strong coloring of individual chromatids or their segments, noticeably different from the color of the rest of the chromosome (or the entire chromosome in a given region). It is observed, for example, when mitotic chromosomes are treated with ethidium or other methylene chlorides; they form highly colored fragments [1][2]. Unlike negative heteropyknosis, in which metaphase fragments of chromosomes in which there are no telomeres are stained, and uniform staining is found in the centromere region and in the region of both arms, with positive heteropyknosis in metaphases, strongly stained areas appear in only one chromatid. This can be one arm of the chromosome or even a separate region of it, or single light-grained sections of both arms [3], in addition, hyperchromatic stripes are observed in the chromatids in the centromere region
