Synthesis of DNA during meiosis.
Chromosome pairing and crossing-over between homologous chromosomes in meiotic cells are two distinctive events which must in some way involve the DNA moiety of the chromosome. Ever since the unambiguous demonstration by Taylor and McMaster' that DNA synthesis occurs during premeiotic interphase, explanations of pairing and crossing-over in terms of DNA synthesis during meiotic prophase have be...
متن کاملSynthesis of Messenger-like Ribonucleic Acid and Protein during Meiosis in Isolated Cells of Trillium Erectum
The synthesis of RNA and protein by cultures of isolated microsporocytes has been demonstrated. The variation in capacities of such cultures to perform syntheses is a function of meiotic stage and parallels the pattern of changes observed for microsporocytes in situ. A principal feature of this pattern is the induction of syntheses during pachytene and diplotene, stages at which the chromosomes...
متن کاملChanges in protein composition of meiotic nodules during mammalian meiosis.
Homologous chromosome synapsis and meiotic recombination are facilitated by several meiosis-specific structures: the synaptonemal complex (SC), and two types of meiotic nodules: (1) early meiotic nodules (MNs), also called zygotene nodules or early recombination nodules, and (2) late recombination nodules (RNs). The former are thought to be nucleoprotein complexes involved in the check for homo...
متن کاملProtein kinases required for proper segregation of chromosomes during meiosis
Cell cycle deregulation and genomic instability play a major role in the aberrant cell proliferation that characterizes tumorigenesis. A novel role of the cyclin e isoform cyclin e2 in these processes is reported in the manuscript " Cyclin e2 induces genomic instability by mechanisms distinct from cyclin e1 " by Caldon et al. 1 in another issue of Cell Cycle, evidence that regulation of cyclin ...
متن کاملReplication protein A is sequentially phosphorylated during meiosis.
Phosphorylation of the cellular single-stranded DNA-binding protein, replication protein A (RPA), occurs during normal mitotic cell cycle progression and also in response to genotoxic stress. In budding yeast, these reactions require the ATM homolog Mec1, a central regulator of the DNA replication and DNA damage checkpoint responses. We now demonstrate that the middle subunit of yeast RPA (Rfa2...
