Point mutation- change in one or a few nucleotides (letters). 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 . Understand how they occur. Analyze the different types of mutations. Understand how mutations affect amino acid sequences and proteins. Objective. Central Dogma. DNA is transcribed into RNA, RNA is translated into proteins. KEY CONCEPT:. . Mutations. are changes in genetic material.. VOCABULARY:. Mutation, point mutation, . frameshift. mutation, polyploidy. Mutations – extension from gene expression. . Changes in genotype. Science. Learning intention. To understand the different types of mutations. . You will need. A pen and a piece of paper or a laptop to record your answers. . You may need the internet to search for answers. . 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.
