Inside every cell, thousands of molecular signals collide, overlap, and compensate, obscuring the true drivers of gene expression.
Add Yahoo as a preferred source to see more of our stories on Google. In 1957, just four years after Francis Crick and other scientists solved the riddle of DNA’s structure—the now famous double helix ...
DNA and RNA methylation, initially thought to operate as distinct pathways, have been shown to interact closely, shifting our understanding of gene regulation. A team of researchers from the ...
A common type of error-correcting mechanism in biology is called kinetic proofreading. For example, if errors turn up when cells are making new DNA, enzymes can cut out incorrect nucleotides. They can ...

RNA strand that can almost self-replicate may be key to life's origins
Life may have begun when RNA molecules began to replicate themselves, and now we’ve finally found an RNA molecule that is very close to being able to do this ...
