*Unit 6 Part 5: Mutations and Gene Technology Flashcards
DNA & Protein Synthesis
A change is DNA sequence is called a _____.
mutation
Some mutations aree caused by external factors called _____.
mutagens
Gene mutations
Changes in small amounts of nucleotides
Point mutation
~One nucleotide is changed to a different nucleotide
~Typically causes no issues
~Ex. Instead of A it is T
Frame shift mutation
~One or more nucleotides are inserted or deleted
~Bigger effect than point mutations because it changes how the DNA code is read
What is another word for point mutation?
Substitution mutation
Chromosome mutations
Affect many genes
Deletion Chromosome Mutation
Gene/genes are missing
Duplication Chromosome Mutation
Extra copies of a gene
Inversion Chromosome Mutation
Genes are backward
Translocation Chromosome Mutation
Genes are switched to a different chromosome
