Exam points

  • Explain that free RNA nucleotides align to the DNA template by complementary base pairing and hydrogen bonding during transcription.
  • Apply DNA adenine–RNA uracil and cytosine–guanine pairing rules to derive the complementary mRNA sequence from a DNA template.
  • Check a transcription representation by matching every base and distinguishing the DNA antisense template from the resulting RNA strand.
