Quick explanation
Describe the components of DNA nucleotides
- This point belongs to Amino acids, proteins and DNA (A-level only), especially DNA chemistry (A-level only).
- You need to be able to describe the components of DNA nucleotides.
- The key ideas to know are nucleotide and DNA.
- Use the linked flashcards and practice questions to check recall, then practise applying the idea in an exam-style answer.
Key concepts
Why it matters
This objective helps connect DNA chemistry (A-level only) to exam-style questions, flashcards, and revision notes for Amino acids, proteins and DNA (A-level only).
Quick student answer
Which of the following components is NOT part of a DNA nucleotide?
Direct answer
D. Ribose sugar
Key terms
- Nucleotide: The basic building block of DNA, consisting of a phosphate group, deoxyribose sugar, and a nitrogenous base.
- Deoxyribose: A five-carbon sugar that is a component of DNA nucleotides.
Common trap
Confusing DNA and RNA components: Remember that DNA contains deoxyribose, which lacks one oxygen atom compared to ribose.
