Document Summary
Please write your name on the first page: find the letter below that best matches the following statements. List three fundamental modules of the translational machinery they would have to change to create cells that read a quadruplet code. (9 pts. ) __i __ a computational tool for identifying potential functional sites. __p__ strength depends on angle as well as distance. __j__ makes pairwise comparisons of protein and nucleic acid sequences. __a__ stabilizes the attached stem ribosome trna aminoacyl trna synthetase (mrna) What is the maximum number of codons available in a quadruplet code? (5 pts. ) Aren"t the 20 biological amino acids enough to encode all the chemical diversity needed for protein structures? (4 pts. ) Nonbiological amino acids with new chemical groups can expand the functional range of proteins. Key practical examples include residues that increase stability or augment chemical reactivity. (new sensors might also be constructed using residues with novel fluorescence emission or regulatory properties.
