**Discontinuous DNA replication in Eucaryotes**
- **Explanation**: Eucaryotes differ from procaryotes in DNA replication by having discontinuous rather than semidiscontinuous replication.
- **Discontinuous Replication**: In eucaryotes, DNA replication occurs discontinuously on the lagging strand. This means that short fragments of DNA called Okazaki fragments are synthesized 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.
- **Semidiscontinuous Replication in Procaryotes**: In contrast, procaryotes have semidiscontinuous replication where the leading strand is synthesized continuously in the 5' to 3' direction towards the replication fork, while the lagging strand is synthesized discontinuously in the opposite direction.
- **Significance**: Discontinuous replication in eucaryotes allows for efficient and accurate DNA synthesis on both strands. It ensures that the lagging strand is also replicated in a timely manner, despite the antiparallel nature of DNA strands.
- **Unidirectional Replication**: Eucaryotes still have bidirectional replication, similar to procaryotes, but the key difference lies in the discontinuous synthesis of the lagging strand.
In conclusion, the presence of discontinuous DNA replication in eucaryotes is a distinguishing feature compared to the semidiscontinuous replication seen in procaryotes. This difference highlights the complexity and efficiency of DNA replication in eucaryotic cells.
