To solve the question regarding which stage of prophase I closely resembles prometaphase of mitosis, we can follow these steps:1. Understand the Context: The question is about prophase I of meiosis, which is different from prop
During spermatogenesis, meiosis is accompanied by a robust alteration in gene expression and chromatin status. However, it remains elusive how the meiotic transcriptional program is established to ensure completion of meiotic prophase. Here, we identify a protein complex that consists of germ-cell-speci...
Sexually reproducing organisms produce haploid gametes through the specialized cell-division process of meiosis. During meiotic prophase, homologous chromosomes pair and undergo synapsis to enable recombination and crossover formation, which underlie reductional chromosome segregation and genetic variation3,4,5...
These MEFs show increased levels of Emi1 in prometaphase, prolonged mitoses, and aberrant centrosome numbers. βTrCP1 knockout mice also show a meiosis I arrest in spermatocytes. We also found that inactivating βTrCP by RNA interference or by overexpression of a dominant-negative βTrCP causes ...
Here, we have investigated the timing of bouquet termination and the progression of meiosis in fission yeast. Live single-cell imaging elucidated that remaining DNA damages from meiotic recombination activate Rad3 and Chk1 to restrain bouquet formation and meiotic prophase. Crucially, CDK1-cyclin B ...
