Five Prokaryote Species (Labeled A-E) Have Been Sequenced

question 217

Short Answer

Five prokaryote species (labeled A-E) have been sequenced.Refer to the table with the findings of the genes they contain.(Note: "x" denotes the species possessing a functional copy of the gene.) Gene 1 is essential for the synthesis of several amino acids.Gene 2 encodes a protein involved in strengthening the cell wall.Gene 3 appears to encode an enzyme, but its function is unknown. One way to obtain clues about the function of gene 3 would be to see what substances species _______ cannot grow on, in contrast with the other species.
