Final answer:
Eukaryotic chromosomal replication occurs bidirectionally and from multiple origins. These origins are known as autonomously replicating sequences (ARS). Replication in eukaryotes is slower than in prokaryotes.
Step-by-step explanation:
Eukaryotic chromosomal replication, like prokaryotic replication, occurs bidirectionally. However, there are some differences in eukaryotic replication. Eukaryotes have multiple origins of replication on each chromosome, whereas prokaryotes have a single origin. These sequence-specific origins of replication are called autonomously replicating sequences (ARS) in eukaryotes. The rate of replication in eukaryotes is slower than in prokaryotes, with approximately 100 nucleotides being added per second.
