In eukaryotes, ribosomal RNA genes (rDNA) encode the major ribosomal RNA molecules and are typically organized into a distinctive genomic structure involving tandem repetition of a polycistronic coding region. Here, we review eukaryotic rDN...

A cell functions as a metabolic economy that parses information on nutrient availability and internal metabolic flux and then converts that to state outcomes that maintain or shift homeostasis. Here, we discuss how the nutrient-signaling ma...

Centromeres are essential chromosomal loci specified epigenetically by CENP-A chromatin, yet they undergo rapid sequence turnover, structural remodeling, and occasional repositioning. In this review, we integrate recent advances enabled by ...
Mitochondrial DNA Inheritance and Germline Purifying Selection: Insights From Drosophila [0.03%]

The mitochondrial genome resides in a highly mutagenic environment and is typically maternally inherited with little recombination, features that should render mitochondrial DNA (mtDNA) prone to the accumulation of deleterious variants. Con...

Genomic imprinting is an epigenetic phenomenon in which chromosome behavior or gene expression depends on whether an allele was paternally or maternally inherited. Imprinting is commonly associated with a placenta or an analogous organ duri...

Nonessential, supernumerary B chromosomes have been an intriguing anomaly known to researchers for over a century. B chromosomes were first identified in insects and have since been discovered in hundreds of species across many different ta...

Telomeres are sequences at chromosome ends that distinguish the natural end from a DNA break. Telomeres shorten at each round of cell division because the replisome cannot completely copy both DNA strands to the very end. This shortening is...
Mechanisms and Evolutionary Advantages of Unlimited Reproductive Lifespans in Naked Mole-Rat Queens [0.03%]

The naked mole-rat (Heterocephalus glaber) defies mammalian norms with lifelong fertility and postnatal oogenesis. Unlike most mammals, which experience reproductive senescence due to depletion of a finite ovarian follicle pool, naked mole-...

Decades of research into the noncoding transcriptome have unveiled a complex, multilayered web of molecular interactions that govern gene expression, protein synthesis, and cellular function, challenging the once-presumed linear simplicity ...
