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 ...

DNA methylation status in a variety of tissues can accurately reveal the age of an animal, but previously discovered epigenetic clocks often aren’t evolutionarily conserved. In a study published today ...

Northwestern Medicine scientists have uncovered new details explaining how poxviruses manipulate host cells to enhance their ...

However, in the half-century since the structure of DNA was first elaborated ... the nucleolus is the structure where rRNA processing and ribosomal assembly take place. Molecules called small ...

The rRNA molecules fold into complex secondary and tertiary structures, forming domains and motifs that are essential for ribosome function. The rRNA structures also provide binding sites for ...

The surprising paradigm shift could lead to much more protective sunscreens and effective skin treatments.

A striking feature of aging across species is the enlargement of the nucleolus, a change in the cellular structure due to ribosomal deoxyribonucleic acid (DNA) instability. In a recent study ...
