Which of the following statements correctly describes one characteristic of DNA replication in eukaryotes?
A)In the leading strand,DNA is replicated in short pieces called Okazaki fragments,which are then joined together at the end of the process.
B)DNA is replicated in the 3' to 5' direction in the leading strand.
C)In the lagging strand,DNA is replicated in short pieces called Okazaki fragments,which are then joined together at the end of the process.
D)Helicase joins the Okazaki fragments together in the lagging strand.

In eukaryotes, DNA replication occurs in a semiconservative manner, where each strand of the original double helix serves as a template for the synthesis of a new complementary strand. However, due to the antiparallel nature of DNA, the two strands have to be replicated in different ways. The leading strand is replicated continuously in the 5' to 3' direction, whereas the lagging strand is replicated discontinuously in the opposite 3' to 5' direction, resulting in the formation of short Okazaki fragments. These fragments are then joined together by DNA ligase to form a complete strand. Therefore, option C is the correct statement describing DNA replication in eukaryotes.
