DNA is fundamental to the biology of all life on Earth, but how many of us actually know what it is or what it's made of?

A DNA sequence is a specific lineup of chemical base pairs along its strand. The part of DNA that determines what protein to produce and when, is called a gene. First established in 1985 by Sir ...

Scientists have provided the most detailed account yet of the earliest stages of DNA replication, an essential process for ...

For the first time, scientists have witnessed the very moment DNA begins to unravel, revealing a necessary molecular event ...

The Pol-theta enzyme (blue) joins two parts of a broken DNA strand (yellow). This process is mutagenic and can give rise to cancer. LA JOLLA, CA—DNA repair proteins act like the body’s editors ...

An mRNA molecule carries a portion of the DNA code to other parts of the cell for processing. mRNA is created during transcription. During the transcription process, a single strand of DNA is ...

RNA polymerase moves along the DNA strand. Free RNA nucleotides form hydrogen bonds with the exposed DNA strand nucleotides by complementary base pairing to form a strand of mRNA: Note - RNA ...
