Prokaryotic organisms have a single origin of replication, whereas eukaryotic organisms have many origins where replication occurs simultaneously. Which of the following is the most probable reason for this observation?
Prokaryotic DNA is much smaller than eukaryotic DNA.

Prokaryotic DNA is much smaller than eukaryotic DNA.

Explanation:

Prokaryotes are microscopic and simple organism and their genetic material is very much smaller than eukaryotes. So as the DNA of prokaryotes is smaller therefore only one origin of replication is sufficient to replicate the DNA in them on time.

As eukaryotes have much larger DNA so one origin of replication is not sufficient to replicate the DNA of eukaryotes until the cell cycle completes, therefore, to complete the DNA replication at the time the DNA must have multiple origins of replication.

hi~~

i would say that hybridization occurs frequently in nature, because there are many types of hybrids that have occurred naturally, such as the mule (male donkey + female horse)
