Zonae pellucidae of metaphase I and metaphase II oocytes were equally penetrable after the salt treatment, whereas penetration occurred only exceptionally when the oocytes were living. These results show that, after in vitro aging and subsequent salt treatment, eventual differences in oocyte maturity ...
Xenopus oocytes arrested in prophase I resume meiotic division in response to progesterone and arrest at metaphase II. Entry into meiosis I depends on the activation of Cdc2 kinase [M-phase promoting factor (MPF)]. To better understand the role of Cdc2, MPF activity was specifically inhibited by...
During meiosis, cells perform two cell divisions: meiosis I and meiosis II. Each cell division can be broken up into P.M.A.T. phases, i.e., prophase, metaphase, anaphase, and telophase. However, the P.M.A.T phases within meiosis I and meiosis II differ slightly. Meiosis...

Related to Metaphase II:Meiosis I meiosis top to bottom:In meiosis a parent cell replicates and recombines, divides once to create two daughter cells, then divides again creating four daughter cells, each of which has half the genetic content of the original parent cell. ...
Answer to: Homologous chromosomes separate and move to opposite poles during: a. anaphase I. b. prophase. c. anaphase II. d. metaphase I. e...

In mammals, journey from metaphase-I (M-I) to metaphase-II (M-II) is important since oocyte extrude first polar body (PB-I) and gets converted into haploid gamete. The molecular and cellular changes associated with meiotic cell cycle progression from M-I to M-II stage and extrusion of ...
Prophase I arrest and progression to metaphase I in mouse oocytes: comparison of resumption of meiosis and recovery from G2-arrest in somatic cells. Mammalian oocytes are arrested at prophase I until puberty when luteinizing hormone (LH) induces resumption of meiosis of follicle-enclosed oocytes. ...
