What Does ORC Stand For?

ORC stands for Origin Recognition Complex

The Origin Recognition Complex (ORC) is a multi-subunit protein complex that plays a critical role in the initiation of DNA replication in eukaryotic cells. It recognizes and binds to specific DNA sequences at replication origins, facilitating the recruitment of additional proteins necessary for the formation of the pre-replicative complex. By ensuring proper timing and regulation of DNA replication, ORC is essential for maintaining genomic stability and cellular function.
