Exam Tips
- Always mention the specific bond type when describing the formation of polymers.
- When describing enzyme-substrate complexes, refer to the tertiary structure of the active site.
- Use the term 'complementary' when discussing base pairing or enzyme-substrate binding.
- Ensure you can distinguish between the roles of DNA helicase and DNA polymerase.
- Practice drawing the general structure of an amino acid and identifying the R-group.
- Use the formula magnification = size of image / size of real object correctly, ensuring units are consistent
Common Mistakes to Avoid
- Confusing condensation and hydrolysis reactions.
- Failing to specify the role of water in condensation/hydrolysis.
- Incorrectly identifying the bonds (e.g., peptide vs phosphodiester).
- Confusing the structure of alpha-glucose and beta-glucose.
- Misunderstanding the role of hydrogen bonds in protein tertiary structure versus DNA double helix.
