Discusses common mutations that occur in the human population and describes the many different types of genetic mutations and their impact.

Explains what genetic diversity is, things that cause it, factors that affect it negatively, and why it is so important. Includes examples of the presence and absence of genetic diversity.

Not all genetic mutations are harmful. Examples of beneficial mutations are described here.

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

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.

Take a closer look into the modern view of evolution. This article includes many pieces of evidence, all which support the theory of evolution.

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

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

Presents information about human chromosomes, their structure, and genetic disorders that can result from mutations.

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.

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.

These pages are part of a site called Evolution that accompany a textbook by the same name. Mark Ridley is the author. This section has an advanced discussion of determining allele and genotype frequencies using the Hardy-Weinberg ratio.
