How to Respond to an Epidemic. Imagine an epidemic so virulent that it is the leading cause of death for children, teens, young adults. It takes 125,000 lives in America alone every year, not to mention causing nearly $80 billion in medical costs.
The origin of replication (also called the replication origin) is a particular sequence in a genome at which replication is initiated. This can either involve the replication of DNA in living organisms such as prokaryotes and eukaryotes, or that of DNA or RNA in viruses, such as double-stranded RNA viruses.
Initiation of eukaryotic DNA replication is the first stage of DNA synthesis where the DNA double helix is unwound and an initial priming event by DNA polymerase Î± occurs on the leading strand. The priming event on the lagging strand establishes a replication fork.he process of semiconservative replication for the site of DNA replication is a fork-like DNA structure, the replication fork, where the DNA helix is open, or unwound, exposing unpaired DNA nucleotides for recognition and base pairing for the incorporation of free nucleotides into double-stranded DNA.
