Final answer:
The antiparallel nature of the DNA molecule in eukaryotic cells affects DNA replication. DNA replication is crucial for a cell's survival because it ensures accurate transmission of genetic information.
Step-by-step explanation:
The antiparallel nature of the DNA molecule in eukaryotic cells affects the DNA replication process in several ways. First, the two strands of DNA are oriented in opposite directions, with one strand running in the 5' to 3' direction and the other running in the 3' to 5' direction. This requires the replication machinery to work in opposite directions on the two strands. Second, the antiparallel nature of the DNA molecule means that DNA synthesis can only occur in the 5' to 3' direction, resulting in the leading and lagging strands during DNA replication.
The DNA molecule is crucial for the cell's survival because it contains the genetic information necessary for the cell to carry out its functions. DNA replication ensures that each daughter cell receives a complete and accurate copy of the genetic information during cell division. Without proper DNA replication, errors can occur, leading to mutations and potentially harmful consequences for the cell and the organism.
