Biochemistry Questions:

If the polynucleotide 5.. AUAUAUAUAUAUAU...3' is used with a mitochondria-derived cell-free protein-synthesizing system, the product is Met-Tyr-Met-Tyr-Met-Tyr Part A What does this say about differences between the mitochondrial and bacterial codes? AUA codes for Tyr, not lle, in the mitochondrion. AUA codes for Tyr, not Met, in the mitochondrion. AUA codes for Met, not lle, in the mitochondrion. AUA codes for lle, not Tyr, in the mitochondrion C UAU codes for Met, not Tyr, in the mitochondrion. C UAU codes for lle, not Met, in the mitochondrion. Submit Request Answer

Explanation / Answer

Part A. AUA codes for Met, not Ile, in the mitochondrion

This occurs because mitochondria codes for a different set of tRNAs.

Part B. all of the above
