DNA REPLICATION

What does "semi-conservative replication" mean?

*Hint: synthesized= created

• One double helix contains one original strand and one newly synthesized strand.

• One double helix contains two original strands, and the other double helix contains two new strands.new double helix contains two original strands

• new double helix contains two original strands

• One double helix contains two newly synthesized strands.

What is the goal of DNA replication?

• to make proteins

• to make RNA

• to proofread the cell cycle

• to ensure every cell has a complete set of identical DNA
