Sentences with phrase «circular chromosome of»

Not exact matches

Most of a bacteria's DNA is found in its chromosome, but bacteria also have many extra, smaller and circular bits of DNA known as plasmids that easily can pass from one bacterial strain to another.

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

Curious about the possibility of circular RNAs contributing to cancer, Pandolfi and his colleagues set out to see if they could detect relevant changes in tumors known to harbor distinct fusion proteins, which result when different chromosomes abnormally join together, melding two separate genes into a new centaur - like gene.

During this stage, the mobilized islands take circular form, independent of the chromosome.

To gain access to the gene - containing portion of the barley genome at high resolution, Close and his team identified and sequenced 15,622 BACs or bacterial artificial chromosomes — small fragments of the barley DNA linked to other DNA to constitute a circular molecule that can replicate and be propagated inside an E. coli bacterial cell, enabling researchers to produce copies of each BAC for DNA sequencing one small piece of the barley genome at a time.

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.

plasmid - A small, circular piece of DNA found outside the chromosome in bacteria.

Among the other 42 gene targets tested, representing genes located within the chromosome, linear plasmids and circular plasmids, gene transcription was detected in both duplicate samples of 22 gene targets in saline - treated mice, particularly in heart base samples.

They use natural plant centromeres (a key part of chromosomes needed for their inheritance), promoters (gene activation sites), and gene - termination sequences to assemble linear or circular minichromosomes that contain at least a dozen genes that can improve crops by promoting traits like pest and disease resistance.

Prokaryotic genetic material is organized in a simple circular DNA molecule (the bacterial chromosome) in the nucleoid region of the cytoplasm.
