Interestingly, PH can spontaneously occur in animal models of impaired DDR. Different groups are defined based on PH etiology. DNA integrity is constantly threatened. Compared to mitosis, which can take place in a matter of minutes, meiosis is a slow process, largely because of the time that the cell spends in prophase I.

As a result, the gametes produced during meiosis are genetically unique. Further studies are then required to fully explain how DNA damage and DDR contribute to PAH pathogenesis in order to identify new therapeutic targets. Hi Subramani, How are extracellular materials transported through vesicles derived from the plasma membrane to lysosomes? Previous Article in Journal. Genetic factors, including spontaneous and inherited mutations, are sometimes responsible, but it is very difficult to assign the exact cause. Meiosis II resembles a mitotic division, except that the chromosome number has been reduced by half. These crossovers are possible because the X and Y chromosomes have small regions of similarity near their tips. Exogenous genotoxic agents refer to environmental events such as exposure to mutagenic chemicals or physical agents like UV or ionizing radiation e.
