Five prokaryote species (labeled A-E) have been sequenced.Below are 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 produces an enzyme that breaks down methane.The functions of the other three genes are currently unknown. Which of these genes is/are likely to be included in the minimal genome?
A) Only genes 1 and 4
B) Only gene 2
C) Only gene 5
D) All of these genes
E) None of these genes
