Mitochondrial Replacement Therapy There are many differing opinions concerning mitochondrial replacement therapy in the United States. Such as the child might have a negative perception of themselves‚ The child may feel disconnected from their mother‚ and they may have issues with their ancestry. Another opinion is the procedure needs to be further tested to ensure MRT’s validity. There are a couple of diseases associated with the mutation in the mitochondria; LHON disease and Leigh’s disease

many types of chemical reactions‚ five general ones of which I will be describing. Chemical changes are a result of chemical reactions. All chemical reactions involve a change in substances and a change in energy. Neither matter nor energy is created or destroyed in a chemical reaction‚ only changed. There are so many chemical reactions that it is helpful to classify them into 5 general types‚ which include the following: synthesis‚ combustion‚ decomposition‚ single-replacement‚ and double-replacement
