origin, Source. Origin denotes the rise or commencement of a thing; source presents itself under the image of a fountain flowing forth in a continuous stream of influences.
Origin of replication
Discrete positions on a chromosome or vector DNA where replications are initiated. Vectors must have at least one origin of replication sequence for their replication in host cells.
