3 of 8 Level 2 1a. Draw in the arrow-pushing for the reaction below, which makes a precursor for the cyanosulfidic synthesis. Label the nucleophile and electrophile in the boxed step, and what is X? © NH4 HN OH © NH NH3 L H₂NO OH HN OH NH2 HO HO NH₁₂ HN © NH4 H₂N HO HO NH3 -X NH4 H₂N 1b. The first step of the reaction is inhibited by excess cyanide anion. What does the cyanide react with (the glycolaldehyde or the aminonitrile)?

3 of 8 Level 2 1a. Draw in the arrow-pushing for the reaction below, which makes a precursor for the cyanosulfidic synthesis. Label the nucleophile and electrophile in the boxed step, and what is X? Θ NH4 NH3 Θ NH Myk HN OH HN NH4 H₂NO OH HN OH NH2 HO H₂N N -- HO HO © NHA H NH₁₂ -X HO NH₁₁ H₂N 1b. The first step of the reaction is inhibited by excess cyanide anion. What does the cyanide react with (the glycolaldehyde or the aminonitrile)? 2.Cyanosulfidic system We are going to assess the Powner-Sutherland synthesis system for its prebiotic plausibility and chemistry. a. What final products do we get out of this synthesis system? b. What are the implications on the RNA world from the fact we cannot currently get RNA purine nucleotides with this synthetic system?
