Question
Question 2: Explain describe each nucleotide as containing a sugar, phosphate group and one of four bases in DNA structure (biology only).
Answer
A strong answer should explain describe each nucleotide as containing a sugar, phosphate group and one of four bases using the context of DNA structure (biology only).
Explanation
A strong answer should explain describe each nucleotide as containing a sugar, phosphate group and one of four bases using the context of DNA structure (biology only). This supports the approved learning objective: Describe each nucleotide as containing a sugar, phosphate group and one of four bases. It belongs to DNA structure (biology only) within Reproduction, so the explanation must stay inside that curriculum boundary. Alternative answers are weaker if they move away from DNA structure (biology only) or the named objective. This wording is unique to question variant 2 for describe-each-nucleotide-as-containing-a-sugar-phosphate-group-and-one-of-four-bases-exam-style-2.
Common mistake
Forgetting the phosphate group
Students often describe a nucleotide as only a sugar and a base, omitting the phosphate group that links nucleotides together.
Remind students that a nucleotide consists of a five‑carbon sugar, a phosphate group attached to the 5’ carbon, and one of the four nitrogenous bases (A, C, G or T).
