Transposons have been found clustered at the chromosome ends in eukaryotic cells, but this is the first time it's been documented in bacteria with linear chromosomes, and the researchers found ...

When bacterial DNA is labeled with radioactive atoms, it takes its own picture. Autoradiographs reveal that the bacterial chromosome is a single very long DNA molecule and show how it is duplicated ...

In some organisms, like humans, chromosomes are linear, but in other organisms, like bacteria, chromosomes are typically circular. In prokaryotes, the circular chromosome is contained in the ...

In a paper published in Science, researchers show that transposons can target and insert themselves at the ends of linear ...

In Streptomyces – historically one of the most significant bacteria for antibiotic development – they found that transposons controlled the telomeres in nearly a third of the chromosomes.

The first-of-its-kind in-depth bacterial evolutionary map could pave the way for the development of precision treatments for certain antibiotic-resistant infections, such as urinary tract infections.

How do bacteria, lacking a nucleus ... Supercoiling explains how chromosomes fit into a small corner of the cell, but how do the proteins involved in replication and transcription access the ...

However, “how much you can extrapolate to [other bacteria] is currently unknown. I think that’s worth further study,” Sheng added. Whether archaea or eukaryotes have a similar process also remains an ...

Now, researchers from Cornell University have uncovered mechanisms by which these mobile genetic elements integrate into the chromosomes of bacteria with linear genomes. “Bacteria are like ...
