Exposure to various chemicals can cause DNA mutations. Classify the examples as representative of transition, transversion, or sertion/deletion mutations. Transition replacement of T:A: with C:G treatment with nitrogen mustard causes this type of mutation oxidative deamination via nitrous acid causes this type of mutation treatment with 5-bromouracil causes the replacement of A:T with G:C Transversion replacement of G:C with T:A Answer Bank Insertion/Deletion the removal of one or more base pairs treatment with proflavin causes this type of mutation

Mitochondrial Mutations

A mitochondrion is a cellular organelle that serves as the site for cellular respiration and energy production (ATP or Adenosine Triphosphate). It is a double-membrane-bound organelle and is only present in eukaryotic cells.
