Which option avoids the common misconception in this objective for Reproduction, Inherited disorders: students must describe cystic fibrosis as an inherited disorder of cell membranes caused by a recessive allele.
- A.Misconception avoided: A DNA base sequence is the storage format; a gene is the named instruction unit. This matches Inherited disorders because students must describe cystic fibrosis as an inherited disorder of cell membranes caused by a recessive allele.
- B.Common misconception: Explaining protein coding without naming the gene as the relevant section of DNA. This would blur DNA vs genes instead of testing Inherited disorders.
- C.Partial misconception: Treating DNA as if it always means one gene. This misses the objective focus on describe cystic fibrosis as an inherited disorder of cell membranes caused by a recessive allele.
- D.Terminology mix-up: It moves into a neighbouring Unit 4.6 idea rather than Reproduction / Inherited disorders.
