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 ...

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 ...

Scientists have finally captured footage of the microscopic machinery that allows our cells to copy DNA—a fundamental process ...

In most animal, plant and fungal cells DNA is stored in the nucleus coiled up in thread-like structures called chromosomes. The nucleus of one of your skin cells contains about two metres of DNA ...

Without her knowledge, one of her colleagues showed the picture to James Watson. When he saw it, he knew that his and Francis Crick’s theory about the structure of DNA was correct. The original ...

(Getty Images) Two new landmark studies show how a seeming tangle of DNA is actually organized ... heart cell requires shifting it from one genetic program to another — each defined by a particular 3D ...

Among the many marvels of life is the cell's ability to divide and thus enable organisms to grow and renew themselves. For ...

MSK researchers shed new light on G-quadruplexes, a type of secondary DNA structure that has attracted attention as a potential therapeutic target in cancer.
