In a study published today (February 14) in Genome Research, researchers describe a new clock, composed of methylation sites in ribosomal DNA. This timekeeper is found in species as diverse as mice, ...

When Blackburn carried out sequencing experiments for the ribosomal DNA minichromosome, she was surprised to find that the telomeres of this structure contained 20-70 tandem copies of a simple ...

But James Watson and Francis Crick's claim was a valid one, for they had in fact discovered the structure of DNA, the chemical that encodes instructions for building and replicating almost all ...

the Bonn researchers have now investigated internal ribosomal entry sites (IRESes). These are specialized, folded sequences within an RNA strand that are particularly well known in the genetic ...
