Replication ... DNA molecule, it continues breaking these hydrogen bonds and separating the two polynucleotide chains (Figure 1). Meanwhile, as the helicase separates the strands, another enzyme ...

They then pull the two strands apart, allowing other enzymes to complete the replication. Without this first step, no DNA can be replicated. In this way, helicases are machines or, because of ...

During DNA replication ... bind to both enzymes. However, that requires us to understand the molecular architecture of DNA helicase. Coordination of DNA Unwinding and Replication is Essential ...

Then a third enzyme, "polymerase," joins the party by attaching to the primer, moving along with the growing strand and adding new letters to form another double helix. In DNA replication ...

Biology lectures teach students that when a cell’s replication machinery comes together, DNA polymerase takes off down the double-helix like a car on a highway ...

Using DNA subunits to create DNA-like superstructures, scientists think they’ve discovered how to turn DNA into enzymes. Scientists dive into the genomes of whales, elephants, and other animal giants ...

Additionally, the scientists unexpectedly captured for the first time a detailed picture of how the "engine" driving the cellular replication machinery moves along DNA in human cells. Their ...

Upon binding, helicases melt the DNA, breaking the chemicals bonds holding the double helix together. They then pull the two strands apart, allowing other enzymes to complete the replication.

The DNA repair and replication pathways converge on a common final step in which the continuity of the repaired DNA strand is restored by DNA ligase, an enzyme that converts nicks ... AMP bound to a 3 ...
