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 ...

Somewhere in the frozen plains of southwestern Russia, a 40-foot circle of mammoth bones and tusks has stood for over 24,000 ...

DNA is found in nearly all living cells ... For instance, most prokaryotes have a single circular chromosome, whereas most eukaryotes have one or more linear chromosomes, which often appear ...

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 essence of CRISPR is simple: it’s a way of finding a specific bit of DNA inside a cell. After that, the next step in CRISPR gene editing is usually to alter that piece of DNA. However ...

The current cost for DNA synthesis is less than $0.1 per nucleotide pair. In step 2, the gene fragment is integrated into a circular piece of DNA, called a plasmid, which is the main delivery vehicle ...

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 ...
