What to Focus On

  • DNA is the genetic material in most organisms.
  • Adenine pairs with thymine and guanine pairs with cytosine.
  • DNA strands are antiparallel.
  • Griffith discovered a transforming principle.
  • Avery, MacLeod, and McCarty showed the transforming principle was DNA.
  • Hershey and Chase proved DNA enters bacteria during phage infection.
  • DNA is more stable than RNA.
  • RNA is the first genetic material.
  • RNA acts as genetic material in some viruses.

Common Mistakes to Avoid

DNA and RNA are basically the same molecule, so either one can serve the same role in all organisms.

The coding strand is the strand that RNA polymerase reads during transcription.

DNA polymerase can start replication on its own and can work in both 5'→3' and 3'→5' directions.
