CNTD1’s crossover act
B efore meiotic divisions, chromosomes form crossovers, which represent the reciprocal exchanges between the DNA molecules of the homolo-gous partner chromosomes. These crossovers aren't just important for reassorting genetic traits; they're essential for the correct alignment and segregation of meiotic chromosomes. To ensure that every homologous chromosome pair forms at least one cross-over—a...
متن کاملCompeting crossover pathways act during meiosis in Saccharomyces cerevisiae.
In Saccharomyces cerevisiae the MSH4-MSH5, MLH1-MLH3, and MUS81-MMS4 complexes act to promote crossing over during meiosis. MSH4-MSH5, but not MUS81-MMS4, promotes crossovers that display interference. A role for MLH1-MLH3 in crossover control is less clear partly because mlh1Delta mutants retain crossover interference yet display a decrease in crossing over that is only slightly less severe th...

To coincide with the introduction in the United States of the Sunshine Act, Genevieve Pham-Kanter discusses what we need to look for to fight hidden bias and deliberate or unconscious corruption. Please see later in the article for the Editors' Summary.
متن کاملCrossover interference
What is crossover interference? During prophase of meiosis in most eukaryotes, DNA recombination events between homologous chromosomes are induced to occur at high frequency, so there are usually multiple events per chromosome pair per meiosis. Whereas many of these recombination events are non-reciprocal, a subset results in reciprocal exchange of genetic material between chromosomes — crossov...
