Answer: The scientist will perform another investigation in order to find out the role of certain genes in disease resistance.
Explanation-
As per the information given in the question, a mice having mutation in ear depicts same pattern of resistance when compared to another mice having normal ears. This indicates that the genes responsible for resistance are not related to genes that result in ear formation.
Therefore, to find out the effect of diet on disease resistance in rats, the scientist will perform another investigation in order to find out the role of certain genes in disease resistance.
The answer is mRNA, I think. mRNA stands for Messenger Ribo Nucleic Acid. it is sent to the cytoplasm to tell the Ribosomes what to do in the development of proteins. It could also be all of the above because all of the RNA molecule probably get moved at one point.
