Gamete (sex or germ) cells. Mutations in somatic cells. Usually result in killing that body cell only.. M. istakes made in the DNA sequencing. They can have a range of effects.. They can affect the genetic information that is passed to offspring.. Cells have evolved various methods to deal with them. . Given a mutation, identify its type. Predict how a mutation will affect a protein.. Mutations. Changes in genetic material (DNA). 2 main types of mutations. Point mutation- change in one or a few nucleotides (letters). 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.. Conditional mutations. Point mutations. In . point mutations . the sequence of the DNA has been altered at a single position. Where this change consists of replacing one nucleotide by another, it is known as a . KEY CONCEPT:. . Mutations. are changes in genetic material.. VOCABULARY:. Mutation, point mutation, . frameshift. mutation, polyploidy. Mutations – extension from gene expression. . Changes in genotype. 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.
