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 ...

Medical researchers have learned more about an enzyme found to be overly expressed in patients with hereditary breast cancer, ovarian cancer, and prostate cancer. Our DNA is not indestructible.

Polymerase chain reaction (PCR) is a fundamental molecular biology tool that scientists use to amplify and analyze genetic material, such as DNA and RNA. PCR involves the enzymatic amplification of ...

The avian influenza virus needs to mutate to cross the species barrier and to infect and replicate within mammalian cells. Scientists have now deciphered the structure of the avian influenza virus's ...
