Mutation May . occur . in:. somatic cells (body cells): . will not be . 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:. What happens if there is a mistake (. mutation. ). in the DNA code?. Possibly proteins won’t be made or are made improperly.. If the mutations occur in the gametes, the offspring’s DNA will be affected positively, negatively, or neutrally.. Ireen Kiwelu.

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.. The types of proteins an organism possesses depend upon the . sequence of nucleotides. The two main types of gene mutations include:. Point mutation: one base pair is replaced for another base pair.. Main idea: Gene expression is regulated by the cell, and mutations can affect this expression. Gene Regulation . Cells have the ability to control which genes are transcribed and when they are transcribed. KEY CONCEPT:. . Mutations. are changes in genetic material.. VOCABULARY:. Mutation, point mutation, . frameshift. mutation, polyploidy. Mutations – extension from gene expression. . Changes in genotype. Author. Ann Brokaw. Rocky River High School. Ohio.
