A specific sequence of bases in a nucleic acid molecule to which the enzymes responsible for replicating the nucleic acid bind to initiate the copying process.
A site at which DNA replication is initiated. There is only one in bacterial chromosomes, but numerous origins in eukaryotic chromosomal DNA.
A site on a DNA molecule where replication initiates.
The point of specific sequence at which DNA replication is initiated.
The origin of replication (also called the replication origin) is a unique DNA sequence at which DNA replication is initiated. DNA replication may proceed from this point bidirectionally or unidirectionally.
