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 ...

Every day, our cells divide. Each time they need to copy both their DNA and the structure in which the DNA is packed. This packaging, called chromatin, acts as a guide. It tells the cell how ...

DNA breaks are toxic lesions for the cell ... This intact homologous copy must therefore be identified within the vastness of ...

DNA stands for deoxyribonucleic acid. Nucleic acids are named for where they're found—inside the nuclei of cells—and for the ...

Within a cell, DNA carries the genetic code for building proteins. To build proteins, the cell makes a copy of DNA, called mRNA.

Most cancers arise when breaks in a cell's DNA go undetected and unrepaired, allowing the damaged cell to churn out defective ...
