Answer:
B.) Replication fork
Explanation:
The replication fork is the point at which two strands of DNA separate via DNA helicase.
The origin of replication is the site on a singular DNA strand where replication begins. Here, complementary nucleotides begin bonding to the single-stranded DNA via DNA polymerase.
The replication bubble is created when DNA helicase separates a DNA strand. The DNA helicase does not separate the entire strand, but rather opens only certain sections at one time. This creates a "bubble" in the DNA strand where replication will take place.
Okazaki fragments are formed on the lagging strand of the single-stranded DNA. Because DNA is only created from the 5' to 3' direction, RNA primase must reposition itself after adding a primer (made of nucleotides). DNA polymerase then fills in these fragments with more complementary nucleotides in small sections.
