how many replication bubbles exist on a single molecule of eukaryotic dna?

a. only 1 bubble
b. 3 bubbles
c. up to 10 bubbles
d. nearly unlimited bubbles

1 answer

In eukaryotic DNA, replication typically initiates at multiple sites along the DNA molecule, resulting in the formation of multiple replication bubbles. Therefore, the correct answer would be:

d. nearly unlimited bubbles

Eukaryotes can have many origins of replication on a single DNA molecule, allowing for efficient replication of their larger genomes.
