(Phys.org) —The ability of a cell to move, replicate, and recast itself according to the needs of the organism which it serves, comes at it price. The extreme flexibility of cells takes its origin from the constant turnover ...
Characteristics passed between generations are not decided solely by DNA, but can be brought about by other material in cells, new research shows.

In a recent paper in RNA Biology, researchers show that mitochondria translocate their key RNA methyltransferase enzyme, TRMT1, into host cell nuclei in response to neural activity. This subcellular relocalization of key ...
New research provides insight into how an enzyme that helps regulate aging and other metabolic processes accesses our genetic material to modulate gene expression within the cell. A team led by Penn State researchers have ...
