Concept essentials

  • DNA polymerase directionality depends on matching each strand, enzyme or laboratory step to its exact function.
  • Template strands and complementary base pairing give dna polymerase directionality its copying accuracy.
  • DNA polymerase directionality is clearer when amplification, separation and profiling are not confused.
  • Molecular evidence for dna polymerase directionality must be interpreted from bands, isotopes, primers or enzyme roles.
