CLAIM: COVID-19 mRNA vaccines alter recipients' DNA by changing its shape to a "triple helix." THE FACTS: There is no evidence that the COVID-19 vaccines are editing humans' DNA, experts have told the ...

Certain DNA sequences can form structures other than the canonical double helix. These alternative DNA conformations—referred to as non-B DNA—have been implicated as regulators of cellular ...

In essence, they took the familiar straight linear DNA double helix and twisted it in either direction once, twice, three times or more and connected the ends together to form a loop. Their previous ...

As a result, the translocated DNA double helix will necessarily split and unwind, an effect known as unzipping. The research team, which also includes Antonio Suma from the University of Bari, ...

Still, if her image led Watson to realize DNA was a double helix, then Watson and Crick committed a faux-pas when they didn't cite Franklin in their landmark paper.

Like roping cattle with a lasso, supercoiled looped DNA captures gyrase in the first step. Gyrase then cuts one double-helix of the DNA lasso and passes the other helix through the break to get free." ...

Historians have long debated the role that Dr. Franklin played in identifying the double helix. A new opinion essay argues that she was an “equal contributor.” By Emily Anthes On April 25 ...
