Because enzymes are little molecular machines, heat cycling is enough to get them to do the work of DNA replication. The process is called the DNA polymerase chain reaction (PCR). (If it sounds ...

What is DNA, and how does it work? You don't need a degree in genetics to understand. Here, we'll give an overview of DNA and ...

One way they do this is to use a DNA microarray to determine the expression levels of genes. When a gene is expressed in a cell, it generates messenger RNA (mRNA). Overexpressed genes generate ...

Who linked DNA to heredity? For multiple decades following ... that protein was not the hereditary material through their work with bacteriophages, which are viruses that infect bacteria (Figure ...

Scientists have provided the most detailed account yet of the earliest stages of DNA replication, an essential process for ...

DNA repair proteins act like the body's editors ... "We now have a much clearer picture of how Pol-theta works, which will enable us to block its activity more precisely," says senior author ...

Sequencers have come a long way since 1986. Back then, Applied Biosystems' first automated DNA sequencer, the 370A, scanned bands coming off the bottom of a slab gel. Yet it was barely automated: ...

DNA repair proteins act like the body's editors ... "We now have a much clearer picture of how Pol-theta works, which will ...

“Human polymerase θ helicase positions DNA microhomologies for double-strand break repair,” include Yonghong Bai, Brian A. Sosa-Alvarado and Timothy Guzi of MOMA Therapeutics. This work was ...
