To answer the question about the different types of mutations, we can categorize them into five main types. Here’s a step-by-step breakdown of each type: Step 1: Deletion- Definition: Deletion is a type of mutation where a segment of the DNA sequence is removed or lost.- Example: If...

The hunt for pathogenic mitochondrial DNA (mtDNA) mutations is often fueled by the seeming novelty of mutations that are either nonsynonymous or affect the protein synthesis machinery in patients. In order to determine the novelty of a detected mutation, the working geneticist nearly always consults...

Point mutations are changes in a single nucleotide, where it can be substituted with another type of nucleotide, deleted, shifted over because of the addition of another nucleotide before it. A change in One Base Causes a Point Mutation Causes of Point Mutation What is a point mutation? A ...
- A point mutation, also called base-pair substitution, is a gene mutation that changes a single nucleotide base pair of DNA or RNA. Point mutations can be categorized based on the impact on protein expression. Silent Mutation: Although a change in the DNA sequence occurs, this type of muta...
