Proteins are polypeptides, numerous amino acids. First Recall Proteins------. **Peptide Bond between amino acids. **Notice the “R” group. It’s a group of molecules that determines the amino acid.. Changes in the genetic material. Mutations can occur in two different types of Cells:. 1. Somatic (body) cells. 2. Gamete (sex or germ) cells. Mutations in somatic cells. Usually result in killing that body cell only.. Point mutations. single base change . silent mutation. no amino acid change. redundancy in code. missense. change amino acid. Changes the final protien. nonsense. change to stop codon. Stopping prematurely . The sequence of bases in DNA are like the letters of a coded message or even the letters of a simple alphabet. . If we change the sequence of the letters do we change the nature of the message?. That . KEY CONCEPT:. . Mutations. are changes in genetic material.. VOCABULARY:. Mutation, point mutation, . frameshift. mutation, polyploidy. Mutations – extension from gene expression. . Changes in genotype. There are two basic types of mutations:. Gene mutations - mutations that produce changes in a single gene. Chromosomal mutations - mutations that produce changes in whole chromosomes. Gene mutations . mutation. Mutations. Actual Mutations . in fruit flies. What is a mutation?. A mutation is any change in a cell’s DNA. A mutation can occur in an individual gene. - results in a single changed protein.
