The correct Answer is:
To solve the question of identifying the incorrect option among the given statements, let's analyze each option step by step. ### Step-by-Step Solution: 1. **Option 1: Recombination and variations, recombination and mutations are phenomena that lead to variation in DNA.** - This statement is correct. Recombination and mutations are indeed processes that contribute to genetic variation. 2. **Option 2: Chromosomal abrasions are commonly observed in cancer cells.** - This statement is also correct. Cancer cells often exhibit chromosomal abnormalities, including abrasions, which can lead to genetic instability. 3. **Option 3: Change in single base pair of DNA is not sufficient to cause mutation.** - This statement is incorrect. A change in a single base pair can indeed lead to a mutation, such as a point mutation, which can affect protein function. 4. **Option 4: Point mutation arises due to change in single base pair.** - This statement is correct. A point mutation specifically refers to a change in a single nucleotide base pair in the DNA sequence. 5. **Option 5: Recombination and recombination, recombination and recombination are caused due to change in single base pair of DNA.** - This statement is incorrect and appears to be repetitive and confusing. Recombination is a process that involves the exchange of genetic material between chromosomes, which is not solely caused by a change in a single base pair. ### Conclusion: The incorrect options are **Option 3** and **Option 5**. However, since the question asks for a single incorrect option, **Option 3** is the most straightforwardly incorrect statement.
