A new study has revealed that certain locations of DNA are copied faster than others, which could also have an effect on mutation rate. Cell division is fundamental for life, allowing organisms to ...

The circadian rhythm is the body's clock, and it influences physiology at the cellular level; it can help animals, including humans, know when it's time to eat, wake up or go to sleep. Recent work has ...

Bacteria are constantly moving with the help of motility organs called flagella or pili to colonize new niches. Also, bacteria can exchange information, like "speaking to each other," and thus acquire ...

Bacteria that are resistant to antibiotics thrive in the face of drug treatment, which can lead to life threatening, often incurable infections. Other bacteria can exist in a pre-resistant state. To ...

Transposons are critical drivers of bacterial evolution that have been studied for many decades and have been the subject of Nobel Prize winning research. Now, researchers from Cornell University have ...

A bacterial protein helps to stop transcription -- the process of making RNA copies of DNA to carry out the functions of the cell -- by causing the cellular machinery that transcribes the DNA to pause ...

Scientists have discovered that bacteria can reshape their DNA to survive dehydration. The research, published today in the journal Proceedings of the Royal Society Interface, shows that bacterial DNA ...

Some genetic disorders—such as cystic fibrosis, hemophilia and Tay Sachs disease—involve many mutations in a person's genome, ...

Inaccuracy of DNA replication poses novel health risk The researchers conclude that – combined with the greater radition risk in space – the inaccuracy of DNA replication under microgravity could pose ...

Scientists from UC San Diego and colleagues in Australia have engineered bacteria that can detect the presence of tumor DNA in a live organism, it was announced Thursday. The innovation, published in ...
