(2015 6E) In the 1960s the molecular biologist George Streisinger developed the strand-slippage hypothesis. Streisinger noticed that mutations occured in areas of DNA that contained many repeated sequences. When a strand-slippage error occurs, an insertion mutation can result. How does the insertion mutation affect the DNA? Answer A Nitrogenous bases are added. B. Nitrogenous bases are exchanged. C Nitrogenous bases are damaged. D Nitrogenous bases are deleted. x x X
