Regarding DNA replication, which, if any, of the following statements is incorrect?

#Unit 3. Fundamental Processes
  1. DNA replication is said to be semi-conservative because for each DNA helix only one strand serves as a template for new DNA synthesis.

  2. The two DNA strands of the parental DNA helix are unwound using a DNA helicase.

  3. The replication fork marks the point at which DNA is actively being replicated from a single DNA duplex to form new DNA strands.

  4. The synthesis of new DNA strands always proceeds in the 5’ → 3’ direction.
