New Look Inside Cell Nucleus Could Improve Cancer Diagnostics

Researchers have sequenced the entire messenger RNA – the “genetic photocopies” – contained in the nucleus of a single cell, a long-anticipated step toward better cancer diagnostics and other medical applications. Researchers have successfully isolated and sequenced the entire messenger … Continue reading

To Cap or Not to Cap: Scientists Find New RNA Phenomenon That Challenges Dogma

COLUMBUS, Ohio – Some RNA molecules spend time in a restful state akin to hibernation rather than automatically carrying out their established job of delivering protein-building instructions in cells, new research suggests. And instead of being a fluke or a … Continue reading
