New study reveals how cells sort out loops meant to encode microRNAs

Just as two DNA strands naturally arrange themselves into a helix, DNA's molecular cousin RNA can form hairpin-like loops. But unlike DNA, which has a single job, RNA can play many parts -- including acting as a precursor for small molecules that block the activity of genes. These small RNA molecules must be trimmed from long hairpin-loop structures, raising a question: How do cells know which RNA loops need to be processed this way and which don't?

Super-resolution microscopes reveal the link between genome packaging and cell pluripotency

In 1953 Watson and Crick first published the discovery of the double helix structure of the DNA. They were able to visualize the DNA structure by means of X-Ray diffraction. Techniques, such as electron microscopy, allowed scientists to identify nucleosomes, the first and most basic level of chromosome organisation

Sall4 protein helps fix DNA damage

A protein that helps embryonic stem cells (ESCs) retain their identity also promotes DNA repair, according to a study in The Journal of Cell Biology. The findings raise the possibility that the protein, Sall4, performs a similar role in cancer cells, helping them fix DNA damage to survive chemotherapy.

Disrupting cancer regulator MYC: an interview with Professor Kim Janda

MYC is an oncogenic member of the basic helix-loop-helix-leucine zipper transcription factor family. In its monomeric form, MYC’s tertiary structure is intrinsically disordered and the protein is transcriptionally inactive.
