The alanine aminoacyl tRNA synthetase enzyme of E. coli recognizes the alanine tRNA only by an unusual G:U base pair at position 70 in the stem of the tRNA. In the laboratory, you make a copy of the alanine tRNA gene that is identical to the wildtype copy except that the anicodon sequence 5' - IGC -3' is replaced with the sequence 5' - UCA -3'. You then add this mutant tRNA gene back into a wildtype E. coli. As a result,

Core Processes:Translation. This is a difficult one, but is actually basic. Just think the process through. Make diagrams - it may help.
This is an example of a difficult question. You can expect one two that demand this level of understanding and analytical skill on the final exam.
The correct answer is: some proteins will be longer than ususal.
