Ribosomal DNA (rDNA) is present in hundreds of copies in the genome, but has not previously been part of genetic analyses. A new study of 500,000 individuals indicates that people who have more copies ...
Hyperthermophilic archaea are true survival experts. They thrive in boiling hot springs and deep-sea vents—environments ...
One small compartment inside the nucleus has come into focus with regards to aging: the nucleolus. Its main job is simple and ...
Computational and genomic tools have enabled researchers to explore the human genome and make many associations between various characteristics and genes or gene variants. But many parts of the human ...
Research from the Stowers Institute provides evidence suggesting that cancer cells might streamline their genomes in order to proliferate more easily. The study, conducted in both human and mouse ...
ATRX (alpha thalassemia/mental retardation X-linked) complexes with DAXX to deposit histone variant H3.3 into repetitive heterochromatin. Recent genome sequencing studies in cancers have revealed ...
Ribosomes are composed of two subunits, the small and large subunits, each containing specific rRNA molecules. The main types of rRNA include: Small Subunit rRNA: In prokaryotes, the small subunit ...
In the absence of SIRT7, a human primary cell displays multiple nucleoli. DNA was stained with DAPI (turquoise) and nucleolus was stained with anti-fibrillarin (red). Disclaimer: AAAS and EurekAlert!
Background and aims – Brachystegia is a species-rich tree genus found in tropical Africa and a typical element of Miombo woodlands, a widely distributed subtype of the Zambezian savanna. Plastid DNA ...
