In biology, a mutation is a randomly derived change to the nucleotide sequence of the genetic material of an organism. Mutations can be caused by copying errors in the genetic material during cell d...

For more information about the types of gene mutations: ... The DNA sequence of a gene can be altered in a number of ways. Gene mutations have varying effects on health, depending on where they occur and whether they alter the function of essential proteins. The types of mutations include:

Plant height mutations could changes a tall plant to a short one, or from having smooth to round seeds. Biochemical mutations have a lesion in one specific step of an enzymatic pathway. For bacteria, biochemical mutants need to be grown on a media supplemented with a specific nutrient.

Each of these mutations occurs in a huge gene that encodes a protein (of 1480 amino acids) called the cystic fibrosis transmembrane conductance regulator (CFTR). The protein is responsible for transporting chloride ions through the plasma membrane.

There are many different ways to alter a gene, just as there are many different ways to introduce typos into a sentence. In the following examples of some types of mutations, we use the sentence "The fat cat ate the wee rat" as a sample gene:

Genetic alterations can be placed into two large categories. The first category is comprised of changes that alter only one or a few nucleotides along a DNA strand. These types of changes are termed point mutations.
