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?

Watson and Crick ultimately used Franklin's images, along with their own evidence for the double-stranded nature of DNA, to argue that DNA actually takes the form of a double helix, a ladder-like ...

For DNA to replicate, the helix must first unwind and break the DNA from a double strand into two single strands. Upon binding, helicases melt the DNA, breaking the chemicals bonds holding the ...

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

A DNA double helix is made of two strands running in opposite directions. Each strand is made of four bases -- A, T, C, and G -- that pair up in specific ways to form rungs along the strands.

But where and how does the famous double helix fit into chromosomes ... We've now zoomed in enough to see portions of the DNA strand. The DNA is wrapped around histones -- protein structures ...

In both cases, replication occurs so quickly because multiple polymerases can synthesize two new strands at the same time by using each unwound strand from the original DNA double helix as a template.

Researchers harness the power of the world’s most advanced supercomputers to simulate the inner workings of cellular ...

For replication to occur, the helix must first unwind ... move along the DNA and continue unwinding the double strand. Rather than prying DNA apart in a single motion, the helicase undergoes ...

Biology lectures teach students that when a cell’s replication machinery comes together, DNA polymerase takes off down the double-helix like a car on a highway ...

The OB domain consists of a five-stranded antiparallel beta barrel plus an alpha helix. Structural Basis for Nick Recognition by a Minimal “Pluripotent” DNA ligase Although ChVLig lacks the large N- ...
