Chromosomes 20
WebChromosome 20p duplication is a rare chromosome abnormality that occurs when there is an extra copy (duplication) of genetic material on the short arm (p) of chromosome 20. The severity of the condition and the signs and symptoms depend on the size and location of the duplication and which genes are involved. WebThe chromosomes begin to decondense and return to their “stringy” form. Cytokinesis, the division of the cytoplasm to form two new cells, overlaps with the final stages of mitosis. …
