Transformation is a process in which bacteria take up new DNA released by dead cells and integrate it into their own genomes.In Streptococcus pneumoniae (which causes many cases of pneumonia, inner ear infections, and meningitis), the ability to carryout transformation requires from 105 to 124 genes, collectively termed the com regulon. The com regulon is activated inresponse to a protein called competence-stimulating peptide (CSP), which is produced by the bacteria and exported into thesurrounding medium.When enough CSP accumulates, it attaches to a receptor on the bacterial cell membrane. The receptor then activates a regulatorprotein that stimulates the transcription of genes within the com regulon and sets in motion a signaling cascade that resultsin transformation.Does the com regulon in S. pneumoniae exhibit positive or negative control? Explain your answer.negative control, wherein CSP is a repressor of the com pathway, which stimulates transcriptionnegative control, wherein CSP activates the membrane receptor, which turns on transcription of various genesO positive control, wherein CSP binds to membrane receptors and stimulates the regulon, which suppresses transcriptionat multiple locicannot be determined because no information is provided about the structural genes involvedO positive control, wherein CSP activates the membrane receptor and turns on transcription at com regulon genes
