PCR

Contributed by Ning Chin Polymerase Chain Reaction (PCR) is one of the most important technique in the field of molecular biology. The idea of PCR came to Kary Mullis in 1983 when he was driving from Berkeley to Mendocino. 34 years later, PCR technique is used heavily and taught to students as a basic molecular […]

Herpesvirus Latency Confers Protection From L. monocytogenes and Y. pestis

Contributed by Azarene Foutouhi Susceptibility to bacterial infections depends on many things including the individual’s immunologic condition and the virulence of the bacteria. After preliminary data showed prolonged macrophage activation during gamma-Herpesvirus latency, researchers wondered if this state might be associated with resistance to infection. Mice five weeks post infection with HV68 or MCMV challenged […]

Genetic memory: accessing the past through our DNA

Contributed by Poyin Chen The premise for the video game, Assassin’s Creed, is based on the technological ability to re-live our ancestors’ experiences by accessing their memories inherited through their DNA. While this is actually scientifically impossible, the concept of heritable “memories” through epigenetic programming is currently an active area of study. A publication by […]

Amylases and their importance during glycan degradation

Contributed by Narine Arabyan Amylases catalyze the cleavage of α-D-1,4 and α-D-1,6-glycosidic bonds in starch and related carbohydrates. Amylases are widely distributed in nature and are important in carbohydrate metabolism. Amylases in Salmonella are poorly characterized glycosyl hydrolases. The importance of amylases during Salmonella infection is understudied, especially as new virulence factors. The genome of […]
