Slow cruciform transitions in palindromic DNA.
Extrusion of cruciform structures in self-complementary regions of DNA is known to be favored by negative supercoiling of DNA. We show here that, in moderately supercoiled DNA, cruciform extrusion is a very slow process. In plasmid pUC7 DNA, with a 48-base-pair palindrome, the half-time of extrusion...
