Scientists Unveiled the Mysterious Procedure in Human DNA Replication According to the report of eLife on April 2, 2013, the long mysterious mechanism in human DNA replication has been identified for the first time. For a long time, the key procedure in DNA replication is being unclear. Either in humans or in other organisms, sliding clamps, the load of molecular structure onto DNA is necessary for part of DNA replication process. Due to the under-standard knowing, the human DNA replication is not well studied. As the above picture shows, the sliding clamp is a ring-shaped protein that acts to encircle the DNA strand, latching around. The sliding clamp then serves to anchor special enzymes-polymerases to the DNA, which ensure efficient copying of the genetic material. Without a sliding clamp, polymerases can copy very few bases every time. But the clamp helps the polymerase to stay in place, allowing it to copy thousands of bases before being removed from the strand of DNA. Du
