A mushroom harboring the Gram-positive bacterium C. fischoederii also harbors the Gram-negative bacterium P. frondae. It is known that very rarely, when those two bacteria co-inhabit a mushroom, a change in P. frondae’s genetic makeup can occur, allowing the mushroom to turn into the tasty blue mushroom known as the Wooly Neptune. What are the three distinct mechanisms that can explain how permanent change in the genetic makeup of P. frondae can occur, allowing it to become blue (and tasty)?

Please explain the write correct answer and explain why(the Answer I selected is wrong)

Line A below shows the peptide synthesized after transcription and translation of a piece of DNA.  Line B shows the peptide synthesized after a mutation in this piece of DNA. proline- arginine - aspartic acid - lysine - glycine proline - glutamine - aspartic acid - lysine — glycine The type of change in the DNA most likely to be responsible for the difference between the peptides is:   a. A frame-shift mutation d. A base deletion b. A base insertion e. A silent mutation f. A base substitution
