To cells that are defective in primer removal, you add fluorescent ribonucleotides when the cells are undergoing DNA replication. In this case, you observe that one strand glows more than the other not only near the replication fork but also at intervals along its length. Which strand glows in this way and why?
a. The lagging strand glows in this way because it is synthesized continuously.
b. The leading strand glows in this way because it is synthesized continuously.
c. The leading strand glows in this way because it is synthesized discontinuously.
d. The lagging strand glows in this way because its RNA primers are required for each Okazaki fragment.

Answer :

The reason the lagging strand lights in this manner is because each Okazaki fragment requires its RNA primers.

what is Lagging strand ?

A single DNA strand called as the lagging strand is replicated in the 5′ - 3′ direction during DNA replication (opposite direction to the replication fork). The lagging strand undergoes periodic infusions of DNA known as "okazaki fragments."

What do you understand DNA synthesis?

DNA replication is the process by which cells obtain a copy of the genome's DNA. A cell must first copy (or reproduce) its entire genome to be able to divide, ensuring that each daughter cell has a complete genome during split.
