WebbDNA Replication: The DNA strand is stored within the nucleus of a cell for protection as well as organization. Once a cell needs to replicate its DNA, it performs meiosis at a certain time so that all is in order. Webb15 mars 2016 · The origins of replication are short sections on a DNA molecule that contain a specific set of nucleotides. Prokaryotic cells will often have only one origin of replication for their ring of DNA. Eukaryotic cells on the other hand can have hundreds to thousands of origins.
