The correct Answer is:
To solve the question of selecting the incorrect statement regarding mutations, we will analyze each statement one by one. ### Step-by-Step Solution: 1. **Understanding the Relationship Between Genes and DNA**: - The first statement claims that the relationships between genes and DNA are best understood by mutation studies. This is true because mutations can provide insights into how genes function and how they relate to the DNA sequence. **Hint**: Consider how mutations can reveal the functional aspects of genes in relation to DNA. 2. **Effect of Large Deletions and Rearrangements**: - The second statement suggests that the effects of large deletions and rearrangements are not easy to comprehend. This is incorrect because while large deletions and rearrangements can be complex, they can often be identified and understood through mutation analysis. Thus, this statement is false. **Hint**: Think about how geneticists analyze mutations and the tools available for understanding complex genetic changes. 3. **Mutations Leading to Loss or Gain of Function**: - The third statement indicates that mutations may result in the loss or gain of a gene and its function. This is a true statement, as mutations can indeed alter gene function, leading to either loss or gain of function. **Hint**: Reflect on how mutations can affect protein synthesis and gene expression. 4. **Point Mutation Definition**: - The fourth statement defines point mutations as changes of a single base pair in a gene. This is also correct, as point mutations specifically refer to alterations at a single nucleotide position. **Hint**: Recall the different types of mutations and their definitions. ### Conclusion: The incorrect statement regarding mutations is the second one: "Effect of large deletions and rearrangements are not easy to comprehend."
