How can biological sequences change?

1. Point mutation or substitution - one base replaced by another

point mutation


2. "Indel"

2.1 Deletion - loss of one or more adjacent bases

deletion

2.2 Insertion - adding one or more bases

insertion


3. Large insertions or deletions

  • Tandem repeats of genes
  • Transposable elements


4. Recombination - crossover and gene conversion (these are like cut-and-paste editing between two very similar texts)

recombination



effects


goto Evolutionary changes
