You may not even have a complete break, but rather just have a crack in the bone. With displaced fractures, on the other hand, your bones shift from their original places and may protrude from your body. A non-displaced fracture is less intense, and is often not seen by the eye.
Think of two separate pieces that are held together by hydrogen bonds. The job of Helicase is to unzip the DNA strand â¦ by breaking the hydrogen bonds that hold them together, and it does this by moving along the strand of DNA, very much like on an actual zipper. Because of this type of movement, helicase is a type of `motor protein.`. 1 person found this useful. Shelley Morton.
Quick Answer. The enzyme DNA helicase unzips the DNA double helix to allow it to replicate. DNA helicase has a rotation speed of 10,000 rotations per minute and moves ahead of the replication fork. It continuously unwinds the DNA strands to allow DNA polymerase to attached new nucleotide strands.
