Bacteria can reshape own DNA

Certain bacteria can reshape its own DNA to avoid dehydration, a study from Monash University researchers shows.

The bacterial DNA can change from B-DNA - the regular double helix - to a more compact variant called A-DNA when subjected to hostile conditions.The researchers used infrared light to investigate the DNA of live bacteria.

The study was led by PhD student and lead researcher Donna Whelan, and Associate Professor Bayden Wood. The findings will help researchers understand how dormant bacteria become active when they move from dry surfaces to more welcoming environments such as the human body.
