Oogenesis - An Overview of Oogenesis and its Process

Oogenesis, ovogenesis, or oögenesis /ˌoʊ.əˈdʒɛnɪsɪs/ is the differentiation of the ovum (egg cell) into a cell competent to further develop when fertilized. It is developed from the primary oocyte by maturation. Oogenesis is initiated in the embryonic stage. Ver mais In mammals, the first part of oogenesis starts in the germinal epithelium, which gives rise to the development of ovarian follicles, the functional unit of the ovary. Oogenesis consists of several sub-processes: … Ver mais BRCA1 and ATM proteins are employed in repair of DNA double-strand break during meiosis. These proteins appear to have a critical role in resisting ovarian aging. However, Ver mais • Anisogamy • Archegonium • Evolution of sexual reproduction Ver mais Oogenesis Oogenesis starts with the process of developing primary oocytes, which occurs via the transformation of oogonia into primary Ver mais Some algae and the oomycetes produce eggs in oogonia.
