PPT-Mutations: Types

and Causes What kinds of mutations can occur Mutations Mutations are changes in the genetic material Mutations can produce changes in a single nucleotide to a whole chromosome Gene Mutations. Changes in . DNA. that affect genetic information. Gene Mutations. Point Mutations – changes . in one or a few. nucleotides. Substitution. THE FAT CAT ATE THE RAT. THE FAT HAT ATE THE RAT. Insertion. Mutations. Hollywood’s images of . 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. Mutations. Any unpredictable change in the structure or amount of DNA of an organism is called a . mutation. . . Most . mutations occur in . somatic (body) cells. and are not passed from one generation to the next. . or. How a perfectly good system can go wrong go wrong go wrong. There are 2 types of mutations. 1)Chromosomal rearrangements. . There are too many or too few chromosomes. (nondisjunction and polyploidy). By Karl . Menzel.

Mutation: . Mistake in replication or environmental effect that results in a c. 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 . 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. 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.. KEY CONCEPT:. . Mutations. are changes in genetic material.. VOCABULARY:. Mutation, point mutation, . frameshift. mutation, polyploidy. Mutations – extension from gene expression. . Changes in genotype.
