(Note that a third model of recombination ... Once access has been gained, Rad51 polymerizes on the DNA strand to form what is called a presynaptic filament, which is a right-handed helical ...

The tethered DNA strand was comprised of a double-stranded (dsDNA ... “This experiment is really the nail in the coffin of this model where everything is sitting stably on the DNA,” van Oijen said. He ...

These predictions were as follows: According to the semiconservative model, after one round of replication, every new DNA double helix would be a hybrid that consisted of one strand of old DNA ...

The study was published in Science Advances. DNA double-strand breaks (DSBs) are one of the most deleterious types of DNA ...
