How does DNA replication give rise to variations?




  • If the daughter cells produced are completely identical to the parent or not depends on how accurately the DNA copy is made .
  • Since no biochemical reaction is completely reliable, some errors are expected to occur in the DNA copying which results in variation
  • Because of these variations, the daughter cells are similar but not completely identical to the parent .
  • If these variations are very drastic, the DNA may not be able to work and the cell dies.
  • These discrepancies form the basis of evolution .
