question 139

Multiple Choice

Recall from the text the example of cell communication in Streptococcus pneumoniae: 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 proteins, how would the rate of DNA uptake be affected when the cells reach high density?

• A)There would be no change in the rate of DNA uptake.
• B)There would be a larger than normal increase in the rate of DNA uptake.
