Question

interestingly, because dna polymerase can only add to the 3 end of the dna molecule, one strand can be built continuously (the lower strand in the image above) and the other strand (the 5 end) must be built in sections, known as okazaki fragments (the top strand in the image above). what do biologists call the fragments that are built during dna replication on the 5 end of the dna molecule? chloroplast fragments mitochondrial fragments okazaki fragments

Explanation:

The text above the question explains that during DNA replication, the strand with the 5' end is built in sections called Okazaki fragments. The other options (chloroplast fragments, mitochondrial fragments) are not related to DNA replication fragments. So the correct term is Okazaki fragments.

Answer:

Okazaki fragments
