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 ...
Your DNA is continually damaged by sources both inside and outside your body. One especially severe form of damage called a double-strand break involves the severing of both strands of the DNA double ...
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 ...
Our genes contain all the instructions our body needs to function, but their expression must be finely regulated to guarantee that each cell performs its role optimally. This is where DNA and RNA ...
Antisense oligonucleotides (ASOs), used to treat genetic diseases, can affect how cells repair damage to their DNA. This is ...

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 ...
A mysterious RNA found in breast cancer led scientists to uncover an entire hidden class of cancer-specific RNAs across ...
