Question

The nuclear genome of a single human cell (i.e., the entire diploid complement) contains about 6.6 billion (6.6 × 109) base pairs of DNA. If synthesis at each replication fork occurs at an average rate of 50 nucleotides per second, all the DNA is replicated in 5 minutes. Assume that replication is initiated simultaneously at all origins. How many origins of replication exist in a human diploid genome?

Answer 1

The human diploid genome can have up to 100,000 origins of replication.

Step-by-step explanation:

In the human diploid genome, there can be up to 100,000 origins of replication.
