How is this different from the Miller-Urey experiments from the 1950s ? I am asking this for someone who is more knowledgeable and technical than me.

"To my understanding" ? Those 1952 experiments yielded 20 amino acids, and this experiment in 2016 to 2019 experiments merely are demonstrating RNA can be made with a similar experiment? Our cells naturally use RNA, specifically mRNA in a "translation" process at the Ribosomes part of our cells where the Amino Acids are used to create longer protein chains.

Am I remembering my AP Biology correctly or did I get something wrong?
