(Phys.org)—Genome editing for purposes of replication and repair is handled by enzymes called endonucleases, which cleave DNA strands at very specific sites. These are called "restriction sites," composed of palendromic ...
Most researchers imagine the initial oxygenation of the ocean and atmosphere to have been something like a staircase, but with steps only going up. The first step, so the story goes, occurred around 2.4 billion years ago, ...
