How "Cellular Butlers" Get Our DNA in Shape
News   Jun 29, 2018

A tremendous amount of genetic material must be packed into the nucleus of every cell—a tiny compartment. By what means are certain regions of this packaged DNA unpackaged and used to manufacture RNA and proteins? New work has shed light on this process, with implications for certain age-related diseases and organ decay.

Protein Protects Against Jumping Genes
News   Jun 29, 2018

Transposons are DNA sequences that have the potential to move to new positions within the genome. Their mobilization in the genome of eggs and sperm can lead to infertility. An RNA-based defense system, the Piwi-interacting RNA (piRNA) pathway, is responsible for the suppression of transposons. A new study has advanced understanding of how Piwi fends off jumping genes.
