In July he and his team announced that they had sequenced all 1.8 million base pairs — the rungs of the DNA double helix, and the letters of the genetic alphabet — that make up the single circular chromosome of Haemophilus influenzae, a bacterium that in its wild form causes ear infections and meningitis.

The genome consists of a single circular chromosome of 2 488 635 bp, with no plasmids.

To do this, the researchers used circular chromosome conformation capture (4C - seq) on mouse liver and kidney tissue.

All genomes consisted of a single circular chromosome, except for A506, which is the only genome containing a plasmid (2).

Each subsequent time a cell divides, these circular chromosomes are torn apart unevenly.

Among the 1.6 million base pairs in H. pylori's circular chromosome are some 1590 genes, many of which code for molecules that help the bacterium colonize the human stomach, reports TIGR molecular biologist Jean - François Tomb.

«Bacteria use DNA replication to time key decision: Bacterial decision circuit makes use of circular chromosome.»

Mitochondria, the energy - generating organelles inside cells, carry a circular chromosome containing genes needed to make the mitochondria and keep them running.

Its circular chromosome is five times smaller than that of larger bacteria such as the gut bug E. coli.

Notably, the CRG team, which counted with the expertise in Mycoplasma from the Serrano's laboratory and the collaboration of the ICREA research professor Marc Marti - Renom at CNAG - CRG, discovered that Mycoplasma's circular chromosome is consistently organised the same way in all the cells, with a region called the Origin (where DNA copying begins) at one end of the structure and the midpoint of the chromosome located at the opposite end.

So to fit inside the cell, the DNA is highly coiled and twisted into one circular chromosome.

In 1993, Goodner read a paper by French researchers reporting evidence that A. tumefaciens had a linear as well as a circular chromosome.

Some 5,400 genes reside on four DNA elements — a circular chromosome, a linear chromosome, and two smaller circular structures called plasmids.

Many bacteria have circular chromosomes and some have linear chromosomes, but Agrobacteria are the only species known to have both structures together.

Its genome contains about 1.7 million base pairs arranged in one circular chromosome and two smaller pieces, or extrachromosomal elements.

The bacterium's genome contains roughly 4,500 genes on one circular chromosome.
