Base pair substitution, deletion, or insertion can all result in mutations in damaged DNA. Point mutations - Point mutations are those involving single-base changes, i.e., changes in just one nucleotide within a gene or chromosome. What is mutation, mechanistically?
Mutation = the gene or chromosome that results from a mutational process 3. a mutant is the organism or cell whose changed phenotype is attributed to a mutation B. Test. Sudden heritable change in genetic material of an organism is called as Mutation.
View Genetics_18_Lecture_Notes from BCOR 101 at University of Vermont. So, mutation is defined as any heritable change in the sequence of nucleotide of DNA. A DNA mutation is a long-lasting alteration to the nucleotide sequence of DNA that can occur during replication and recombination. Mutation is an abrupt qualitative or quantitative change in the genetic material of an organism.
