(a)
Interpretation:
The amino acid is selected by mRNA codon GAA has to be predicted.
Concept introduction: DNA sequence is always synthesized in
The nucelotide triplet that encodes an amino acids is called codon. Each group of three nucleotides encodes one amino acid. There are 20 amino acid present which are encoded by differnet codon. DNA sequence is always synthesized in
(b)
Interpretation:
The sequence in the original DNA that led to the codon being present in the mRNA has to be predicted.

- Write structural formulas for the major products by doing addition reactions 1. You must add H2 as Pt is catalyst it does not take part in reactions only speed up the process H₂ CH2=CH-CH3 Pt 2. Add HCI break it into H and Cl CH3 HCI 3. Add Br2 only CC14 is catalyst CH3-CH=CH2 B12 CCl4 4. Add water to this and draw major product, H2SO4 is catalyst you have add water H20 in both the reaction below H₂SO4 CH3-CH=CH2 CH3 H2SO4/H₂O CH3-C=CH2 reflux ?arrow_forwardPlan the synthesis of the following compound using the starting material provided and any other reagents needed as long as carbon based reagents have 3 carbons or less. Either the retrosynthesis or the forward synthesis (mechanisms are not required but will be graded if provided) will be accepted if all necessary reagents and intermediates are shown (solvents and temperature requirements are not needed unless specifically involved in the reaction, i.e. DMSO in the Swern oxidation or heat in the KMnO4 oxidation).
