A guinea pig was injected with radioactive amino acids. Thirty minutes later, tissue analysis showed that protein of the ribosomes had over twice as much radioactivity per gram as the protein of any other part of the cell. What can be concluded from this experiment? Why?

Mutation occurs.

Explanation:

Mutation occurs in the tissues that receives radiations because the production of proteins by ribosomes increases. In normal conditions, ribosomes produces normal amount of protein but in this case proteins production increases by the tissue due to exposure to radioactive amino acid that causes mutation in the ribosomes and it increases its protein production.

i think the answer would be d
