Why is it important to for dna to be duplicated before mitosis

If DNA never replicated, meiosis andmitosis would slowly halve the size of the genome until each cell would die, which probably would not take long. Therefore, it is important that DNAdoubles itself to account for the cells splitting during mitosis/meiosis. DNA replication is similar to RNA transcription.

Distillation is a method of separating mixtures based on differences in volatilitilies of components in a boiling liquid mixture. Sublimation : Sublimation is the process of transition of a substance from the solid phase to the gas phase without passing through an intermediate liquid phase .
