3’ GGTTCCGTACGATATATTATTGG 5’ mRNA is SS molecule that carries information from DNA and carry it further to make proteins. For DNA 3’-5’, mRNA will be CCAAGGCAUGCUAUAUAAUAACCPro-Arg-His-Ala-Ile-Ile-ThrThis change will change the sequence of amino acid replacing Alanine with Glycine, hence altering the final product i.e., protein. This type of mutation is called as ‘Point Mutation’.This change will change the sequence of amino acid replacing isoleucine with Lysine, hence altering the final product i.e., protein. This type of mutation is called as ‘Point Mutation’.
