Question 30
BTMCQ2 marksNeeds review
W, X and Y are the intermediates in a biochemical pathway as shown below:
S ⋯→ W → X → Y → Z
Mutants auxotrophic for Z are found in four different complementation groups, namely Z1, Z2, Z3 and Z4. The growth of these mutants on media supplemented with W, X, Y or Z is shown below (Yes: growth observed; No: growth not observed):
Mutants | W | X | Y | Z |
|---|---|---|---|---|
Z1 | No | No | Yes | Yes |
Z2 | No | Yes | Yes | Yes |
Z3 | No | No | No | Yes |
Z4 | Yes | Yes | Yes | Yes |
What is the order of the four complementation groups in terms of the step they block?
