After DNA damage, for example by chemicals, the damaged and undamaged DNA strands are separated from each other during cell division. The cells often do not repair the DNA damage immediately; the ...

Scientists show DNA polymerases can build long, patterned DNA without a template, opening new paths for synthetic biology and ...

Mutations are changes in the molecular "letters" that make up the DNA code, the blueprint for all living cells. Some of these changes can have little effect, but others can lead to diseases, including ...

Artificial DNA letters beyond A, T, G, C break a fundamental pairing rule to produce nanostructures with new shapes, far greater durability, and an unexpected ability to self-sort.
