Question

1. Instead of directing the synthesis of a polypeptide, Har Khorana found that the RNA (GAUA)_ndirected the synthesis of tripeptides (peptides made of three amino acids) in a cell free translation system. How can this result be explained?
2. Calculate the minimum number of codons required fro an overlapping triplet code to account for the observation that every amino acid can occur as a C-terminal (and N-terminal) neighbor of any other amino acid within polypeptides. Explain how you arrived at your result. What does the result say about the possibility of an overlapping triplet code?
