The first photographic evidence of this shape was obtained in 1952, when scientist Rosalind Franklin used a process called X-ray diffraction to capture images of DNA molecules (Figure 5).

In the folded fork structure shown in the inset, the lagging-strand DNA polymerase remains tied to the leading-strand DNA polymerase. This allows the lagging-strand polymerase to remain at the ...

But James Watson and Francis Crick's claim was a valid one, for they had in fact discovered the structure of ... Wilkins were studying DNA. Wilkins and Franklin used X-ray diffraction as their ...

Rosalind Franklin, from the King's College team, made an X-ray diffraction image of DNA, which is known as Photograph 51. This showed that DNA had a helix shape. Without her knowledge, one of her ...

Switchback DNA has only two strands, so it can be directly compared with the double helical structure of DNA that everyone is ...

DNA test kits that trace maternal and paternal lineage, like mtDNA and Y-DNA tests, can potentially go back thousands of years, offering insights into ancient ancestry far beyond recent generations.
