With the technique called polymerase chain reaction (PCR), scientists can make multiple copies of a specific genetic sequence within DNA. PCR is a powerful tool for researchers because it allows ...

The 11-second clip -- which kind of looks like something pulled from a 1970s video game-- shows glowing strands of DNA stretching from left to right as it duplicates. Using sophisticated imaging ...

Replication is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules. DNA replication is one of the most basic processes that occurs within a cell.

A new method for mapping torsion provides insights into the ways that the genome responds to the torsion generated by RNA polymerase II.
