How purple corn and RNA break genetic laws

Scientists have discovered that an enzyme called RNA-dependent RNA polymerase is needed for paramutation, a phenomenon where one version of a gene can order another to act differently. This finding has significant implications for breeding better crop plants and unraveling complex genetic diseases, including some human health conditions.

The logic of life brings order to our genes

Professor Carsten Peterson and his team demonstrate how genes interact to produce stable systems, using the fruit fly as a model organism. They found that canalyzing rules, where one controlling gene activates another without affecting it, are present in almost 200 genetic networks in fruit flies.

How streptococci go for the throat

Streptococcal bacteria use the bacterial capsule containing hyaluronic acid to bind to epithelial cells of the pharynx and cause sore throats. Suppression of CD44 levels or use of antibodies/ exogenous hyaluronic acid can block this interaction.
