These experiments also allowed them to create artificial RNAs of defined sequences and create a library of artificial polyribonucleotides that were used by Nirenberg by helping him support the hypothesis that RNA plays a key role in the synthesis of proteins using information from DNA.
These experiments also allowed them to create a library of artificial RNA strands of defined sequences, such as a molecule made of only triplets of uracil that would code for phenylalanine. These artificial polynucleotides where used by Nirenberg to support the hypothesis that RNA plays a key role in the synthesis of proteins using information from DNA.
