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.
Cell division (above) can be a matter of simple fission, as described on this page, which occurs only in prokaryotes. Or it can occur via either of the two more complex processes, meiosis and mitosis, characteristic of eukaryotes. Before fission can occur, the cell must replicate its chromosome, which is circular. This process starts when a replication bubble opens in the DNA of the chromosome. There is normally a single origin of replication in prokaryotes, not multiple ones as is the case in eukaryotes.
