When bacteria cells replicate, they do so a little differently than human cells do. They don't undergo mitosis, a splitting that involves construction of spindles to carefully separate the DNA after ...

In many bacteria, the DnaA protein, responsible for chromosome replication initiation, also acts as a transcription factor regulating its own gene expression and the expression of other loci. Here, we ...

If you are anything like us, whenever you plan a journey, you spend a remarkable amount of time thinking about the start and the middle. Is everything packed? What time should we leave? Will there be ...

Bioinformaticians have established that the genes in bacterial genomes are arranged in a meaningful order. They describe that the genes are arranged by function: If they become increasingly important ...

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 ...

ITHACA, N.Y. -- Transposons, or “jumping genes” – DNA segments that can move from one part of the genome to another – are key to bacterial evolution and the development of antibiotic resistance.

Agrobacterium tumefaciens magnified 15,000 times in an image captured earlier this year with a scanning electron microscope at Iowa State University's Roy J. Carver High Resolution Microscopy Facility ...
