Why is it important that human chromosomes have many origins of replication
8_murik_8 [283]

Answer:

Chromosomes contain very large genetic information which would take many hours to replicate with only one origin.

Explanation:

Human cells are eukaryotes, meaning that the genetic information is compressed in chromosomes, that at the same time are contained in the nucleus. As the replication requires all the genetic information to be copied, the length of it would take several hours to complete this task. Therefore, with many origins of replication, this process happens faster and more effectively.
