Question

For each protein, identify its targeting pathway: the sequence of cellular locations in which the protein is found from when translation is complete until it reaches its final (functional) destination. (Note that if an organelle is listed in a pathway, the location implied is inside the organelle, not in the membrane that surrounds the organelle.) What does this experiment reveal about the nucleotide composition of coding triplets for these six amino acids? Select all that apply. AAA - lysine 1C2A (AAC, ACA, CAA) - glutamine, histidine 1C2A (AAC, ACA, CAA) - threonine, proline CCC - lysine 2C1A (CCA, CAC, ACC) - glutamine, proline 2C1A (CCA, CAC, ACC) - glutamine, asparagine 1C2A (AAC, ACA, CAA) - glutamine, asparagine 2C1A (CCA, CAC, ACC) - histidine, threonine 2C1A (CCA, CAC, ACC) - threonine, proline CCC - proline AAA - proline 1C2A (AAC, ACA, CAA) - histidine, threonine

Explanation / Answer

amino acid relationships.

For example, when A and C were mixed with polynucleotide phosphorylase, the resulting RNA molecules contained eight different triplet codons: AAA, AAC, ACC, ACA, CAA, CCA, CAC, and CCC. These eight random poly(AC) RNAs produced proteins containing only six amino acids: asparagine, glutamine, histidine, lysine, proline, and threonine.artificial RNAs containing defined proportions of two or three different bases. As previously mentioned, polynucleotide phosphorylase joins nucleotides randomly; as a result, these artificial RNAs contained random mixtures of the bases in proportion to the amounts of bases mixed. Hence, the resulting products provided clues that the researchers could use to deduce potential codon–.
