A) have many origins of synthesis, while circular bacterial DNA usually have only one.

D) are synthesized dispersively, while circular bacterial DNA is synthesized semi-conservatively.

Question

Quizplus · Accepted Answer

Linear eukaryotic DNA molecules indeed have many origins of synthesis to ensure that their long DNA strands can be replicated efficiently and completely during the S phase of the cell cycle. In contrast, circular bacterial DNA typically has a single origin of replication from which DNA synthesis proceeds bidirectionally until the entire molecule is replicated. This difference is crucial for the replication process in these organisms due to the varying complexities and sizes of their genomes.
