Metabolic fingerprinting: Using proteomics to identify proteins in gymnosperm pollination drops
Proteins are vital parts of living organisms, performing a variety of essential functions such as DNA replication, catabolizing reactions, and responding to stimuli. The complete set of proteins expressed in an organism at ...

Head-on collisions between DNA-code reading machineries accelerate gene evolution
Bacteria appear to speed up their evolution by positioning specific genes along the route of expected traffic jams in DNA encoding. Certain genes are in prime collision paths for the moving molecular machineries ...

Dual systems key to keeping chromosomes intact
USC scientists have discovered how two different structural apparatuses collaborate to protect repetitive DNA when it is at its most vulnerable – while it is being unzipped for replication.

Flipping the 'off' switch on cell growth
A protein known for turning on genes to help cells survive low-oxygen conditions also slows down the copying of new DNA strands, thus shutting down the growth of new cells, Johns Hopkins researchers report. Their discovery ...

Chromosome 'anchors' organize DNA during cell division
For humans to grow and to replace and heal damaged tissues, the body's cells must continually reproduce, a process known as "cell division," by which one cell becomes two, two become four, and so on. A key ...

Researchers find algal ancestor is key to how deadly pathogens proliferate
Long ago, when life on our planet was in its infancy, a group of small single-celled algae floating in the vast prehistoric ocean swam freely by beating whip-like tails, called flagella. It's a relatively unremarkable tale, ...

A pathway to bypass DNA lesions in the replication process is experimentally shown
DNA lesions are really common —about one million individual molecular lesions per cell per day— because its long strands usually have one missing base or are damaged. These lesions can stall the DNA replication ...
