Types of Mutations (HSC SSCE Biology): Flashcards

Any change in the DNA sequence

Mutations caused by environmental factors (chemicals/radiation)

Change in a single base pair in DNA sequence

Large changes moving whole blocks of genes around

One nucleotide base swapped for another

Insertion/deletion shifting the genetic reading frame

Amino acid codon changed into a stop codon

Mutation in egg/sperm cells, can be inherited

Section of DNA removed and not replaced
