What is the origin of replication?

The origin of replication is a specific sequence in a genome where DNA replication begins. In prokaryotes, it typically consists of a single origin, while eukaryotes contain multiple origins to facilitate the replication of larger genomes. At the origin, proteins recognize the sequence, unwind the DNA, and recruit the necessary machinery to initiate the synthesis of new DNA strands. This process is crucial for cell division and maintaining genetic stability.
