Circular DNA, thought to be an accidental byproduct, is borrowing the cell’s DNA repair mechanisms to copy itself DURHAM, N.C. -- Like its viral cousins, a somewhat parasitic DNA sequence called a ...

A plasmid is a small, circular, double-stranded DNA molecule that is distinct from a cell's chromosomal DNA. Plasmids naturally exist in bacterial cells, and they also occur in some eukaryotes.

Did you know that you have a second genome? Small cellular organelles called mitochondria contain their own circular DNA. What happens to your cells when this DNA mutates? Similar to the nuclear ...

Scientists from Flinders University in Australia have made a surprising discovery about a recently identified type of genetic material called circular RNAs. Their research suggests that these ...

Imagine a breakthrough in cancer treatment where only malignant cells are targeted, sparing healthy host cells; or patients with abnormal protein synthesis are treated to produce a healthy protein.

which provides strength and support to the cell. Large circular DNA molecule Bacteria do not have a nucleus and their genetic material (DNA) is not arranged into chromosomes. Cell membrane ...

Such in vitro extracts allow protein production from linear or circular DNA, in quantities large enough to purify and analyze. This tack also provides a way to incorporate modified amino acids into ...

Instead of the linear chromosomes found in mammals, the team crafted a circular chromosome, which is compatible with DNA replication in yeast. They then assembled the HAC inside budding yeast. By ...

Prof. Burstein explains, "Plasmids are small, circular, double-stranded DNA molecules classified as 'mobile genetic elements.' Like viruses, plasmids move from one cell to another, but unlike ...

Every living organism falls into one of two groups: eukaryotes or prokaryotes, with cellular structure determining which group an organism belongs to. Prokaryotes are unicellular and lack a nucleus ...
