Recall from the text in the example of cell communication in streptococcus pneumoniae that the rate of dna uptake by pneumococcal cells increases sharply when they are at high density, due to changes in gene expression brought about by signaling between cells. if the pneumococcal cells did not express receptor protein, how would the rate of dna uptake be affected when the cells reach high density?
