This means that one strand's sugar-phosphate chain runs in ... Crick were pursuing a definitive model for the stable structure of DNA inside cell nuclei. Watson and Crick ultimately used ...

During cell division the two strands separate and on each strand a new "other half" is built, just like the one before. This way DNA can reproduce itself without changing its structure -- except ...

But James Watson and Francis Crick's claim was a valid one, for they had in fact discovered the structure of DNA, the chemical that encodes instructions for building and replicating almost all ...

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 ...

Earlier that morning, in the nearby Cavendish laboratory, the two scientists had discovered the structure of deoxyribonucleic acid, or DNA. This discovery changed the world of science and medicine ...

Cells go to great lengths to maintain the integrity of this vast store of information. They constantly untangle knots in the ...

Cells use many complex genetic repair backup systems to fix DNA damage and remain healthy throughout their lives.

A comprehensive review titled "From the Test Tube to the Cell: A Homecoming for DNA Computing Circuits?" published Mar. 4 in ...

Most cells in the human body each contain about six feet of DNA. Yet the nucleus, where DNA is coiled, is no larger than a ...

In the double helix structure of DNA, thymine forms a base pair with adenine through two hydrogen ... DNA polymerase enzymes use the existing DNA strand as a template and add the complementary ...
