### Genetic Influence on Enzyme Synthesis#### Additional Gene W and Its Effect on Enzyme SynthesisA study has found an additional gene, called W, that influences the synthesis of enzymes 1 and 2. In this context, a strain identified as mutant d exhibits a recessive mutation in gene W.#### Genotype and Enzyme Activity Data TableBelow is a detailed table representing different strains and their corresponding genotypes and enzyme activities, both in the presence and absence of a substance called fictamine.| Strain | Genotype | Enzyme Activity ||-------------|--------------------|---------------------------------|| | | Without Fictamine | With Fictamine || | W | X | Y | Z | Enzyme 1 | Enzyme 2 | Enzyme 1 | Enzyme 2 ||-------------|----|----|----|----|-----------------|-----------------|-----------------|-----------------|| Wild-type | + | + | + | + | ++ | ++ | -- | -- || Mutant a | + | – | + | + | -- | -- | -- | -- || Mutant b | + | + | – | + | -- | ++ | -- | -- || Mutant c | + | + | + | – | ++ | -- | -- | -- || Mutant d | – | + | + | + | ++ | ++ | ++ | ++ |##### Descriptions of Table Contents:1. **Strains**: This column lists the different genetic strains studied - wild-type, mutant a, mutant b, mutant c, and mutant d.2. **Genotype**: The genotype of each strain is represented by a '+' or '–', indicating the presence or absence of the active form of genes W, X, Y, and Z, respectively.3. **Enzyme Activity**: - Enzyme activity is measured both in the presence and absence of the substance fictamine. - Symbols indicate the level of enzyme activity: '++' signifies high activity, '--' signifies no activity, and intermediate levels or observations are adjusted accordingly.##### Key Findings:- The wild **Problem Statement:** The phenotype of a double mutant, \( W^- X^- \), is shown below. Choose the single regulatory scheme above that is consistent with all of the data. Explain your answer briefly.**Data Table:**| | **genotype** | **enzyme activity** | |:-------------:|:--------------------------------:|:---------------------------:|| **strain** | W | X | Y | Z | without fictamine | with fictamine || | | | | | 1 | 2 | 1 | 2 || **mutant 5** | – | – | + | + | ++ | ++ | ++ | ++ |**Explanation of the Data:**- The table lists the data for a double mutant strain referred to as "mutant 5."- The columns under "genotype" describe the presence (+) or absence (–) of four genetic elements (W, X, Y, Z).- The columns under "enzyme activity" display the activity levels of two enzymes (1 and 2) without and with the presence of a substance called fictamine.- Enzyme activities are denoted with "++," indicating a high level of activity.**Task:**To identify the regulatory scheme that corresponds to the observed data, one must understand how the genotype (presence or absence of W, X, Y, or Z) influences the enzyme activities.**Observations:**- Mutant 5 lacks both W and X, but retains Y and Z.- Despite mutations in W and X, enzyme activity for both enzymes (1 and 2) is high (++) with and without fictamine.**Conclusions:**The consistent enzyme activity suggests that W and X do not directly control the activity of enzymes 1 and 2, independently or in combination. Instead, Y and Z may either be directly enhancing enzyme activity or compensating for the absence of W and X.Therefore, the selected regulatory scheme should consider the possibility that Y or Z override the absence of W and X in maintaining high enzyme activity. Without additional regulatory pattern diagrams, it is challenging to provide the exact scheme, but the outcome suggests Y and Z have a more significant regulatory role in enzyme expression or activation.
