Reactions of alkenes and alcohols (chemistry only)
Question
- A. Amino acids
- B. Nucleotides
- C. Fatty acids
- D. Monosaccharides
Answer
The correct option is Nucleotides.
Explanation
The correct option is Nucleotides. Nucleotides is correct because it directly supports the approved learning objective to dNA encodes genetic instructions for the development and functioning of living organisms and viruses. This belongs to Polymerisation and naturally occurring polymers within Reactions of alkenes and alcohols (chemistry only), so the answer must use the correct organic chemistry context. The other options are incorrect when they confuse the organic family, formula type, reaction condition, product, or property being tested. Keep molecular formula, structural formula, displayed formula, and general formula distinct. Do not confuse alkanes with alkenes, saturated with unsaturated, cracking with combustion, polymers with monomers, or hydrocarbons with oxygen-containing alcohols and carboxylic acids. When formulae are used, preserve the stored notation exactly and explain the GCSE chemistry idea in words rather than using unsupported displayed-formula diagrams.
Common mistake
Misunderstanding DNA Function
Students often confuse DNA's role as a carrier of genetic information with its physical structure, thinking that DNA itself is the instructions.
Clarify that DNA is the molecule that encodes genetic instructions, while the instructions are derived from the sequence of bases within the DNA.
