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 strand, ...

Before a cell divides, its DNA is replicated so that each daughter cell inherits the same genetic information. The two copies ...

As DNA strands ravel and unravel in an intricate dance, one notable event takes center stage: replication. This process is essential to life, but the finer details of its orchestrated steps are still ...

Humans and baker's yeast have more in common than meets the eye, including an important mechanism that helps ensure DNA is copied correctly, reports a pair of studies. The findings visualize for the ...

During replication, 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 ...

Half a century ago, scientists Jim Watson and Alexey Olovnikov independently realized that there was a problem with how our DNA gets copied. A quirk of linear DNA replication dictated that telomeres ...

BLOOMINGTON, Ind. -- Research at Indiana University has identified a genetic mechanism that is likely to drive mutations that can lead to cancer. The study, published today in the Proceedings of the ...

Nanoscale “robots” made of DNA that rapidly self-replicate could be harnessed to manufacture drugs or other chemicals inside the body, say researchers. Tiny machines made of DNA origami may make ...
