The availability of large-scale protein-protein interaction data has led to the recent popularity of the study of protein interaction networks. Just as the enormous amount of available sequence ...

DNA repair proteins act like the body's editors, constantly finding and reversing damage to our genetic code. Researchers have long struggled to understand how cancer cells hijack one of these ...

By using enzymes to remove the DNA, they would end up with their protein of interest. To keep the protein-DNA bonds stable, they used ultraviolet (UV) light, which induces crosslinks between proteins ...

Scientists at Scripps Research have now captured the first detailed images of the DNA repair protein, Pol-theta, in action, ...

A new structural blueprint paves the way for improved targeting of cancer cells, particularly those with BRCA1 and BRCA2 ...

All biological function is dependent on how different proteins interact with each other. Protein-protein interactions facilitate everything from transcribing DNA and controlling cell division to ...

So how does protein synthesis make hair? If you've looked at the activity (or even the text version of the activity), you know how a section of DNA instructs a cell how to make a protein.

This process of protein synthesis occurs in two stages - transcription and translation. When a gene is to be expressed, the base sequence of DNA is copied or transcribed into mRNA (messenger RNA).

DNA is the molecule that holds the instructions ... process by which specific genes are activated to produce a required protein. Cellular differentiation When cells express specific genes that ...

Free radicals are produced in the body during normal cellular metabolic activities, and their excessive accumulation can overwhelm the natural antioxidant mechanisms. This leads to oxidative stress, ...
