Which one of the following most closely approximates the number of replicons in a human focus of replication? a. 1b. 50c. 100d. 300e. 30 000

The answer is:

E. 30,000

Since a replicon is known as the amount of DNA which is replicated from a single ori. Since bacteria only have one ori, they only have one replicon. The human genome has approximately 30,000 ori, so there will also be 30,000 replicons in a human focus.
