Which of the following statements is FALSE? Gram positive bacteria with a low G/C to A/T ratio are classified as Firmicutes. Streptococcus and Staphylococcus genera are both gram positive Gram positive bacteria with a high G/C to NT ratio are classified as Actinobacteria Mycoplasma pneumoniae can cause a mild disease called "walking pneumonia". The "G/C ratio" refers to the molar ratio of Guanine compared to that of Cytosine.
