    Mechanisms underlying genome instability mediated by formation of foldback inversions in Saccharomyces cerevisiae

    Bin-zhong Li et al.
    Genetic analysis combined with whole genome sequencing elucidates mechanisms and pathways that form and prevent a specific class of genome rearrangements, foldback inversions, seen in many human cancers.

    CMG helicase disassembly is controlled by replication fork DNA, replisome components and a ubiquitin threshold

    Tom D Deegan et al.
    Ubiquitylation of the CMG helicase is inhibited throughout the initiation and elongation phases of chromosome replication by the DNA structure of a replication fork.

    The nucleosome DNA entry-exit site is important for transcription termination and prevention of pervasive transcription

    A Elizabeth Hildreth et al.
    Disruption of the nucleosome DNA entry-exit site causes readthrough transcription of terminators, decreased nucleosome occupancy, and pervasive noncoding transcription, demonstrating this nucleosomal region protects the genome against inappropriate transcription.

    Differentiating Drosophila female germ cells initiate Polycomb silencing by regulating PRC2-interacting proteins

    Steven Z DeLuca et al.
    Characterization of Drosophila female germ cell differentiation shows that nurse cells initiate Polycomb silencing by regulating Pcl and Scm levels to alter the biochemical properties of the PRC2 H3K27 methylase.

    Harmful DNA:RNA hybrids are formed in cis and in a Rad51-independent manner

    Juan Lafuente-Barquero et al.
    RNA does not form DNA:RNA hybrids in trans that compromise genome integrity.

    Caenorhabditis elegans nuclear RNAi factor SET-32 deposits the transgenerational histone modification, H3K23me3

    Lianna Schwartz-Orbach et al.
    H3K23me3 is a RNAi-mediated transgenerationally heritable heterochromatin mark in Caenorhabditis elegans.

    A mechanism for the extension and unfolding of parallel telomeric G-quadruplexes by human telomerase at single-molecule resolution

    Bishnu P Paudel et al.
    Human telomerase unfolds and extends parallel G-quadruplexes using a unique mechanism involving its RNA template.

    Mitochondrial volume fraction and translation duration impact mitochondrial mRNA localization and protein synthesis

    Tatsuhisa Tsuboi et al.
    Mitochondria can tune the protein synthesis of nuclear-encoded proteins through condition-dependent mRNA localization that is regulated by translation elongation and the geometric constraints of the cell.
