Quizplus · Accepted Answer

The data only provide information about the size of the proteins and the total number of specific amino acids present. This information is not enough to conclude whether the two proteins are the same or not, as it does not reveal anything about the sequence of amino acids in each protein. Therefore, option D is the correct choice. Option A is incorrect because proteins with the same size and total number of amino acids can still have different sequences. Option B is incorrect because the table only gives information about the presence and number of specific amino acids, not all amino acids. Option C is incorrect because identical proteins can be produced in different tissues, and it is not uncommon to find identical proteins across different species. Option E is incorrect because the table does provide information about the number of other amino acids, but this information alone is not sufficient to conclude that the proteins are the same.
