You may think that a virus is a virus, and they all afflict living things more or less the same. Yet while it is true that viruses attack most everything on Earth, the viruses that do the vexing ...
New findings suggest the end-replication problem, an old standby of biology textbooks, is twice as intricate as once thought. Half a century ago, scientists Jim Watson and Alexey Olovnikov ...
Biology lectures teach students that when a cell’s replication machinery comes together, DNA polymerase takes off down the double-helix like a car on a highway ...
