  • False

Pregunta 5

Pregunta
What is the role of each peptide produced by S.aureus?
Respuesta
  • Stimulates other strains that produce the same peptide
  • Inhibits other strains that produce the same peptide
  • Stimulates other strains that produce different peptides
  • Inhibits other strains that produce different peptides

Pregunta 6

Pregunta
P2 & P3 are divergent promoters (they go in opposite directions)
