Question
Transcribed Image Text:A bacterial culture is heated up, resulting in protein denaturation and loss of protein function, including proteins necessary for metabolism of certain nutrients. The cellular DNA remains intact and unchanged.
- Genotypic Change Only
- Phenotypic Change Only
- Both Genotypic and Phenotypic Changes
- Neither Genotypic nor Phenotypic Change
**Explanation:**
In this scenario, the bacterial culture experiences protein denaturation due to heat, affecting the structure and function of proteins. Since the cellular DNA remains unchanged, the genotype is unaffected. However, the phenotype, which includes the observable characteristics such as the ability to metabolize certain nutrients, is altered due to the loss of protein function. Therefore, this situation represents a phenotypic change only.
