Figure 4: Reduction of spontaneous SOS induction from DSEs in cells having DNA Pol III with altered ... Many conditional replication mutants show chromosome breakage 21, implying that altering ...

In E. coli and other bacteria, the DNA double helix closes into a circle, like a twisted rubber band. Replication of the E. coli chromosome can happen in as short as 20 minutes in a test tube.

E. coli has a circular chromosome, but replication doesn’t occur clockwise around the ... and some regions of the DNA are more tightly packaged than others, so this form of gene regulation might be ...

Failures in DNA replication can lead to cancer ... the researchers were able to watch DNA from E. coli bacteria as it replicated and measure how fast enzyme machinery worked on the different strands.

She has studied how the pathogenic bacterium Escherichia coli reacts when exposed to ... When the bacterium is about to ...

"It's a different way of thinking about replication that raises new questions ... the researchers were able to watch DNA from E. coli bacteria as it replicated and measure how fast enzyme ...

Interestingly, cohesion occurs much more strongly in some regions of the E. coli chromosome ... generated and what role they play in faithful chromosome replication, repair and segregation. DNA ...

The researchers created a miniature laboratory where DNA polymerase from Escherichia coli went through one round of replication during the portion of a flight in which weightless conditions would be ...
