Scientific paper on DNA replication & gel electrophoresis

... bp lengths of the newly replicated strand every 1 minute for 6 minutes. Strands that migrated to the top of the gel indicate a stalled replication fork. This was the bulk reaction. -Then used gel-filtration chromatography to remove all unbound proteins and then readded only the 3 proteins that ...

Re: Question for experts: Helicases

... the DNA molecule. How? Does it split in two, or are there more helicases that enter into the picture. The only thing I can find is that it makes a fork in the DNA and a really cheap animation. Maybe they don't really know in detail. Anyway it amazes me that one could handle 3b nucleotides before ...
