Question

Quizplus · Accepted Answer

Replication in fission yeast cells is initiated at specific sites called replication origins, where prereplication complexes have previously assembled. These origins are located at specific DNA sequences, which are recognized by proteins involved in replication initiation. Unlike in bacterial cells, where replication can initiate at multiple sites on the circular chromosome, eukaryotic cells typically have many replication origins that are activated in a regulated manner to ensure accurate and timely replication.
