DNA replication

• Why does DNA need to replicate?

  Because two copies of DNA are needed before mitosis or meiosis for the original and new cell.
• What is conservative replication?

  -a completely new, double stranded copy of DNA is made

  -the parental DNA is conserved

  -results in 1 new and 1 original DNA molecule
• What is dispersive replication?

  -two DNA molecules are produced that contain both parental and new DNA in each polynucleotide chain
