This section contains links to resources that explain the relationship between DNA, genes and chromosomes, the function of DNA and how changes to genetic information can contribute to disease.
The InnovAIT article 'What causes genetic disorders?' provides an overview of genetic concepts.
A very useful introduction to core genetics concepts, 'understanding genetics' is part of the 'Screening Choices' package, a resource aimed at healthcare professionals offering antenatal and newborn care.
Giving a basic overview of genes, mutations and patterns of inheritance, this genetics primer is part of the Genetics, Disease and Dentistry project undertaken by the National Coalition for Health Professionals Education in Genetics (NCHPEG - USA).
This 'Tour of the Basics' is aimed at high school students but may be useful as an animated introduction to core genetics concepts. It was produced by The Genetic Science Learning Centre at the University of Utah (USA).
The Genetics Home Reference site (USA) is aimed at patients but the on-line handbook has useful descriptions of:
'Zoom in on your genome', a flash animation from the Wellcome Trust, explains the structure of DNA by moving from an organ, through to a cell, through the nucleus, to a chromosome and then to DNA.
'Gene structure' and 'gene expression' from the Wellcome Trust give basic descriptions using scientific terms of gene structure and expression.
The Genetics Home Reference on-line handbook (USA) provides more in-depth information on how changes to the genetic material occur and how they can affect health.
