Presentation Transcript

1. Gene Mutation and Molecular Medicine

Gene Expression: Protein Synthesis and Genetic Mutation

Why make proteins?. Proteins are made of 20 kinds of amino acids linked together in a specific order. (2 or more polypeptides).All organisms contain and make proteins. Major structural components of your cells, and your body as a whole. i.e., keratin- hair, fingernails, hemoglobin- rbc's, insulin

Gene Mutation

Gene Mutation . Mutation. Mutation: change in DNA sequence Causes of mutation:. Spontaneous Mutation. Spontaneous mutation in gene for a blood clotting factor, leading to hemophilia. . Point Mutations. Point mutation: change in one or a few DNA nucleotides. Substitutions .
