Explanation:
Semiconservative and Semi-discontinuous DNA Replication:
- DNA replication is semiconservative, meaning that each newly synthesized DNA molecule consists of one original (parental) strand and one newly synthesized (daughter) strand.
- The process is also semi-discontinuous because DNA synthesis occurs in a discontinuous manner on the lagging strand, while it occurs continuously on the leading strand.
- On the leading strand, DNA polymerase synthesizes DNA continuously in the 5' to 3' direction, following the replication fork as it opens.
- On the lagging strand, DNA polymerase synthesizes short fragments called Okazaki fragments in the 5' to 3' direction away from the replication fork. These fragments are later joined together by DNA ligase to form a continuous strand.
Therefore, DNA replication is best described as semiconservative and semi-discontinuous, as it involves both continuous and discontinuous synthesis of DNA strands.
