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? - mitochondrial fragments - okazaki fragments - chloroplast 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. Mitochondrial and chloroplast fragments are not related to this DNA replication concept. So the correct term is Okazaki fragments.

Answer:

B. Okazaki fragments (assuming the options are labeled as A. mitochondrial fragments, B. Okazaki fragments, C. chloroplast fragments; if the original options have different labels, adjust accordingly, but based on the content, the correct one is the option with "Okazaki fragments").
