Effect of small polyanions on retroviruses

A retrovirus is a virus that inserts a copy of its genome into the DNA of a host cell that it invades, thus changing that cell's genome. Once inside the host cell's cytoplasm, the virus uses its reverse transcriptase enzyme ...

New laser to watch DNA-proteins interactions

Researchers have found a new way to study how the DNA and proteins interact inside a cell structure. These reactions last only a fraction of a second, and therefore required a new approach to conventional observing methods. ...

Microbial genomes help propose phylum name

At the phylum level, the number and diversity of unknown microbes still far outnumber those being studied. Metagenomics and single-cell genomics are tools helping researchers learn more about the "biological dark matter" ...

Temperature controls the genetic message

Alternative splicing, the mechanism enabling a gen to encode different proteins, according to the cell's needs, still holds many secrets. It has transformed the initial theory of one gen, one protein, but how it is controlled ...
