Practice dna structure and replication answer key
The picture above shows the replication fork in the DNA replication process. The replication fork is the point where the DNA double helix is unwound and the new strands are being synthesized. It is formed by the separation of the two parental DNA strands, and it moves along the DNA molecule as replication proceeds.DNA Replication Prior to cell division DNA has to make a copy of itself= DNA Replication Follows a template mechanism for this process much like a photograph is made from a photo negative. More than a dozen enzymes are involved in the process. It is fast and amazingly accurate- errors occurring in only about one of a billion nucleotides ...DNA is naturally found as a double-helix, but for it to replicated it must first be unwound so that DNA replication proteins can access the two strands. The double-helix structure of DNA is very stable, and after being unwound for DNA replication to occur, the two strands can easily return to the double-helix structure.
