My name is Stephanne Lim, and I am a freshmen attending John F. Kennedy High School. I am currently enrolled in the Genetics course which has extensively covered molecular genetics. Despite this, there are stil a few questions that remain unanswered. Of course, my paramount question is: Why do different types of nitrogen bases, in different sequences still stand for the same amino acid? I have learned about how both DNA and RNA are composed of nucleotides. The bases in the nucleotides, in sets of three, compose amino acids. How is it that different sequences of different bases still compose the same amino acids? Your time is greatly appreciated.

Sincerely, Stephanne Lim c/o Ms. ST. John
