Ans: There are following importance of dna copying in reproduction:

  • The chromosomes in the nucleus of a cell contain information for the inheritance of features from the parents to the next generation in the form of DNA molecules.
  • So, the first importance of DNA copying is that the characteristics of the parent organism are transmitted to its offsprings.
  • When the DNA already present in the nucleus of a parent cell is copied by making more of DNA by certain biochemical reactions, then slight variations come in the two copies formed.
  • These slight variations in the copying of DNA molecules lead to slight variations in the offspring produced. Thus, another importance of DNA copying is that some variations are produced in the offsprings during reproduction which form the basis for evolution.
