Researchers pulled off a first-ever scientific feat, recording video of a single DNA molecule replicating itself. All living organisms feature this biological process, and understanding how it works in greater detail could lead to a host of new discoveries in biology and medicine.
The historic footage revealed surprising information that challenges what we previously knew about this essential fact of life.When cells divide, DNA replication is necessary for each new cell to have a full copy of our genome, the human genetic code that contains about 3 billion base pairs. The scientists from University of California, Davis used advanced imaging technology to observe DNA extracted from E. coli bacteria.
They used fluorescent dye to light up DNA strands and found that the process features much more randomness than they anticipated.
Here’s what the…
