13. The following diagram shows the normal sequence of a particular protein, along with several mutant versions of it: For each mutant, explain what mutation at the DNA and protein level occurred in the coding sequence of the gene, where (...) denotes a multiple of three unspecified bases. To solve this problem you must show the sequence of DNA that was changed to give rise to the change in the proteins. The difference between the normal DNA and each mutant DNA is a single bp. Normal Met-Gly-Glu-Thr-Lys-Val-Val-...-Pro Mutant 1 Met-Gly Mutant 2 Met-Gly-Gly-Asp
