In the fungus Neurospora, a metabolic pathway synthesizes the amino acid Z (which is essential for its survival) from the precursor W. The intermediates X and Y are also produced in this pathway. The enzymes E1, E2, and E3 catalyze three reactions in the process, as shown: E1 E2 E3
W → X → Y → Z
X-ray radiation can be used to create a mutant strain of Neurospora that has a defective gene sequence for E2.
Based on this scenario, the mutant strain will survive on media that contain:
Selection Bias
a distortion in statistical analysis resulting from the method of collecting samples.
Random Sample
A sample selected from a larger population in such a way that every member has an equal chance of being chosen.
Selection Bias
occurs when the sample is not representative of the population being studied, potentially leading to distorted conclusions.
Skin Cancer
Skin cancer is a form of cancer that originates in the cells of the skin, often due to overexposure to ultraviolet radiation from the sun or tanning devices, leading to abnormal cell growth.
