The diagram below represents a single celled organism a dividing by mitosis to form so I will be in C so it’s a BNC I’ll produce proteins ask what can be best be inferred from this observation A. Protein X is found in every living organism

B. The gene for protein X
is only in this organism

C. Cells A, B and C ingest food to get protein X

D. The gene to produce protein X was passed from cell A to cells B and C during mitosis
