Nobody’s perfect all the time . About 1/10 billion base pairs end up with a error or mutation . Mutation: Mistake in DNA replication or an environmental effect that . results. in a change to the nitrogenous bases in DNA or RNA. . 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 . Small-scale mutations. Missense mutations. Nonsense mutations. Silent mutations. Frameshift mutations. Large scale mutations. Causes. Mutagens. The results of mutation. Mutations. Genetic mutations are changes in the DNA sequence, caused by various mechanisms.. MISTAKES IN DNA. A MISTAKE CAN BE:. 1. A point mutation – substitution, addition, or removal of a single DNA base.. 2. A . frameshift. mutation – . a point mutation due to an addition . or deletion of a DNA base that causes a major change in the genetic code.. 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. .
