Look at the model of DNA Replication, What does semiconservative mean?

• In DNA replication, semiconservative refers to the process where each new double helix contains one old strand and one new strand.
• Involves the complete breakdown of the original DNA strand.
• Semiconservative means both strands are newly synthesized.
• Each new double helix contains two old strands.

During which phase of mitosis do the sister chromatids separate and move towards opposite poles?

• Prophase

• Metaphase

• Anaphase

• Telophase
