Question
Intermediate: A B C D Amino Acid E
Strain 1 + + - + +
Strain 2 + + - - +
Strain 3 - - - - +
Strain 4 - + - - +
+ indicates growth - indicated no growth
Based on this information, construct the biochemical pathway for E synthesis. Show the order of the intermediates and the step that is blocked in each mutant strain
Explanation / Answer
From this chart, we can clearly see that Strain 1 requires everything but intermediate C; thus, intermediate C must come first in the biochemical pathway. We can also see that Strain 4 requires no other medium but B; therefore, B is the last intermediate before Amino Acid E. From Strain 2, it is apparent that A and B are subsequent, as are C and D. From this gathered group of information, you can deduce that the biochemical pathway for Amino Acid E is as follows: C --> D --> A --> B --> Amino Acid E Strain 1 is blocked at the production of D Strain 2 is blocked at the production of A Strain 3 is blocked at the production of C Strain 4 is blocked at the production of B Hope this helps!
