Answer:
a. Prokaryotes have replicons
Step-by-step explanation:
A replicon is a RNA molecule or DNA molecule that posses its own replication origin and can replicate on its own.
Prokaryotes only possess a single replicon compared to eukaryotes with several replicons. In other words, the prokaryotes replicon is the whole chromosome, while eukaryotes have a large number of replicons.
Prokaryotes have fewer types of DNA polymerses, while eukaryotes possess a large range of DNA polymerases which include the five famimilies of DNA polymerases.
