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 ...

DNA strand displacement circuits are inching closer to becoming cellular machines. Scientists are finding ways to make these programmable nanodevices stable and functional inside living cells. If ...

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.

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.

RNA consists of only one strand, unlike the double-helix of DNA. RNA molecules are also significantly shorter in length. Despite these differences, both types of nucleic acid are made from the ...

A molecular construction crew then assembles the missing halves of the strands, turning a single DNA helix into two ... aren't good at staying on the DNA strand. They require CTF18-RFC in humans ...

Study reveals alpha-synuclein's role in enhancing DNA repair in melanoma, linking Parkinson's protein to cancer cell survival ...

Researchers harness the power of the world’s most advanced supercomputers to simulate the inner workings of cellular machinery that repairs DNA and helps prevent life-threatening diseases. Sunburn and ...

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 ...

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 ...
