Final answer:
The lagging strand is synthesized in short stretches called Okazaki fragments on the strand that runs 5' to 3' away from the replication fork. Without the depicted sequence, the exact top or bottom strand cannot be determined, but the lagging strand is synthesized in the 5' to 3' direction complement to the template strand.
Step-by-step explanation:
In the process of DNA replication at the origin of replication (ori), there are two template strands with opposing orientations due to the antiparallel nature of DNA. DNA polymerase, which facilitates the synthesis of new DNA strands, can only add nucleotides in the 5' to 3' direction. Therefore, the strand that runs in the 3' to 5' direction in relation to the replication fork becomes the template for the leading strand, which is synthesized continuously. Conversely, the strand running 5' to 3' becomes the template for the lagging strand, which is synthesized discontinuously in short stretches known as Okazaki fragments. Without seeing the depicted DNA sequence, it is not possible to determine which is the top or bottom strand, but the lagging strand will be the one that is synthesized in the direction away from the replication fork.
To determine the sequence of the newly synthesized lagging strand, we would need to identify the sequence of the template strand and construct a complementary sequence in the 5' to 3' direction, ensuring we label the 5' and 3' ends correctly.
