True
Explanation - A hypothesis is given once the question is identified and background research has been done. A hypothesis is validated by performing experiments.
Prior to the experiments being performed, proper planning is done. After the experiment is carried out, the data is noted. Once the data is noted, results are inferred.
If the evidence agrees with the prediction then the hypothesis is being supported and validated. If the result fails to validate the hypothesis then the hypothesis need to be abandoned or modified.

Answer:
A) histone coding genes
Explanation:
Histones are the proteins involved in the packing of DNA in eukaryotes. They are positively charged proteins and are not found in bacteria. To analyze the evolutionary relationship in a gene between eukaryotes and bacteria, one must choose the gene present in both of them. The tRNA, rRNA and hexokinase encoding genes are common to both bacteria and eukaryotes. Therefore, one of these genes may be chosen for the study. However, histone encoding genes are not present in the genomes of bacteria. Therefore, the study of the histone encoding gene would not be useful for the mentioned purpose.
