Sometimes, DNA is called "semi-conservative." Why might this be?

• The old strand is "conserved" and used to make the new strands
• Uracil is "conserved" in that it is only used to make the new strands
• ATP is "conserved" via the usage of facilitated diffusion
• Ligase is "conserved" in that it is denatured by the process
