Once scientists have zeroed in on a specific segment of DNA, how do they produce enough copies of that segment for their research? In most cases, the polymerase chain reaction, or PCR, is their ...

Determining the number of copies of a double stranded DNA template (be it genomic DNA, plasmid or an amplified fragment) is essential for many genetic quantification applications in research and ...

Pancreatic cancer’s deadly resilience may be tied to extrachromosomal DNA, which allows tumor cells to rapidly adapt to ...

However, the presence of nucleosomes and the folding of chromatin into 30-nanometer fibers pose barriers to the enzymes that unwind and copy DNA. It is therefore important for cells to have means ...

Scientists suggest understanding ecDNA’s role in pancreatic cancer could potentially guide future strategies for making ...

Pancreatic cancer is one of the deadliest cancers worldwide, with a five-year survival rate of 13%. This poor prognosis stems ...

Ribosomal DNA (rDNA) is present in hundreds of copies in the genome, but has not previously been part of genetic analyses. A new study of 500,000 individuals indicates that people who have more ...

A new study has been published in Nature Communications, presenting the first comprehensive atlas of allele-specific DNA ...

Replication of DNA DNA replication is the process by which a cell makes an identical copy of its DNA. Gene expression Only a fraction of the genes possessed by any particular cell will be expressed.
