👉 In molecular biology, a heterosome is a type of cell that contains two identical sister chromatids. These cells are typically found in eukaryotic cells, such as those found in plants and some animals, where they play a role in gene expression and cell division. The definition of a heterosome is: - It is a cell containing two identical sister chromatids (sister chromatids are the chromosomes that contain genetic material). - The sister chromatids have been separated by an interphase region
