The question is incomplete as it does not have the options. The options of the given question are:
1. whether the gene is methylated.
2. relationship between two species.
3. effects of mutation on gene function
4. amino acid sequence of the protein
Answer:
The correct answer will be option-1
Explanation:
A gene is the physical segment of the DNA which determines the trait of the organism.
Since gene represents the sequence of DNA which acts as the genetic material of the organism, therefore, studying the DNA can help determine the effect of the mutation. DNA is a universal molecule therefore studies can help find the relationship between two species. The DNA codes for protein therefore amino acid sequence can be traced.
The methylation of the gene is a post-translational event and controls the expression of gene therefore option-1 is the correct answer.
