1a obtains. At this juncture the nascent lagging strand has not yet caught up with the stalled leading strand. There are many different pathways that can be operative once the replisome has stalled ...

During DNA replication, the unwinding of strands leaves a single strand vulnerable. How does the cell protect these strands from damage? How would you identify the protein that serves as a ...

DNA polymerases are positioned on each strand of DNA . Using a microscope slide as an anchor, we tethered DNA to a bead and stretched it with a flow of solution. We tracked how the position of the ...

Focusing on the schematic illustration in a, two DNA polymerase molecules are active at the fork at any one time. One moves continuously to produce the new daughter DNA molecule on the leading ...

the helix structure is unwound special molecules break the weak hydrogen bonds between bases, which are holding the two strands together this process occurs at several locations on a DNA molecule ...

“It’s a different way of thinking about replication that raises ... Hundreds of Unintended Mutations in DNA Instead, the progress of the “lagging strand” polymerase looks a lot like ...
