Researchers solve a protein complex's molecular structure to explain its role in gene silencing
A cell's genome maintains its integrity by organizing some of its regions into a super-compressed form of DNA called heterochromatin. In the comparatively simple organism fission yeast, a cellular phenomenon known as RNA ...

Study reveals new role for RNA interference during chromosomal replication
At the same time that a cell's DNA gets duplicated, a third of it gets super-compacted into repetitive clumps called heterochromatin. This dense packing serves to repress or "silence" the DNA sequences within -- which could ...
