These class notes from a Microbiology course at Acadia University outline point mutations, frameshift mutations, mutagens, mutation rate, and mutant isolation. A good way to review already learned concepts.

Understand how mutations occur, and the implications.

This site explores the history and the science of DNA. Content also examines and considers the possibilities of genetic engineering and mutation.

Scientific information about the hereditary material in all living things, DNA. Also includes links to fact sheets for quick reference.

This website provides an answer to the following question: "What are Gene Mutations?" Many links are provided throughout this short description that access information on related subjects.

Provides a great overview of DNA damage from agents such as ultraviolet light, nuclear radiation, and certain chemicals. Includes DNA strand drawings.

Good explanation of the different types of mutations. Solid background on base-pair substitution.

Provides some very straight forward information regarding genetic information an DNA. Find out about synthesizing proteins, the Central Dogma of molecular biology, and much more.

This article explains how and why mutations are so important to genetics.

This site explains genetic beliefs before and after Mendel, and also includes a section on Mendel himself and his experiments, entitled, "The Monk and his Peas".

An interactive website that explores information about genes, mitosis, meiosis, cloning, and gene mutation. Concepts are discussed in detail with an interactive glossary and animations. At the end of each section quick questions are...

Explains what chromosomes are, their structure, their functions within a cell, and the health impact of mutations in a gene sequence.

A stop codon is a nucleotide triplet in messenger RNA that signals the end of a protein during the translation process. Read about how this works, the different types of stop codons, and how a mutation can sometimes occur.

A start codon is a nucleotide triplet in a genetic sequence that occurs at the start of a protein's synthesis. Read about how this works and how a mutation can sometimes occur.

Try this interactive module from the Brooklyn College to help understand the genetic code and how changes in the code effect the final protein product.
