Answer: a. 16. At what temperature does annealing of DNA and primer take place? a) 54°C. b) 96°C. c) 42°C. WebAn initiation reaction must occur to functionalize a monomer unit before the reaction can begin. Once a monomer has been functionalized, another monomer unit can bind to it, and the functionalized carbon center propagates to the new monomer unit. In this fashion, monomer units continue to attach to the polymer chain until termination occurs.
