To carry out their experiment, the researchers used a circular piece of DNA, attached to a glass slide by a short tail. As the replication machinery rolls around the circle, the tail gets longer. They ...

During circular DNA replication, the excised primer is readily replaced by nucleotides, leaving no gap in the newly synthesized DNA. In contrast, in linear DNA replication, there is always a small ...

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. But when a circular chromosome is ...

To divide and reproduce, bacteria must make a duplicate copy of their DNA. Because replication of circular bacterial DNA always initiates at one particular point, Narula surmised that the location ...

Nucleoids in mitochondria do need to be circular in order for the machinery that copies their DNA to work. Transcription in mitochondria is directly coupled to replication, and also requires ...

Scientists successfully induced gene expression from a DNA and evolution ... translated proteins by using a circular DNA carrying two genes necessary for DNA replication (artificial genomic ...

Extrachromosomal DNA (ecDNA) is a unique form of circular DNA that exists outside ... However, the molecular mechanisms governing ecDNA replication and maintenance—and their functional ...

This illustration of the replication cycle for circular bacterial DNA shows how Bacillus subtilis bacteria use the ratio of proteins KinA to Spo0F to time their decision to form spores.

Circular DNA, thought to be an accidental byproduct ... CITATION: “Retrotransposons Hijack alt-EJ for DNA Replication and eccDNA Biogenesis, ” Fu Yang, Weijia Su, Oliver W. Chung, Lauren Tracy, Lu ...

Extrachromosomal circular DNA (ecDNA ... amplified tumours is that their cells tend to be under high levels of DNA replication stress, making them genomically unstable, but also less likely ...
