Understanding how chromosomes, DNA and genes all work together can be confusing. The author has explained how chromosomes fit into the picture in clear language.

This website offers a clear definition of the science of Genetics, highlighting DNA and genes. There is a neat, easy-to-understand animated tour of the basics and an opportunity to go inside an animated cell. Student can build a DNA...

This informative resource features an overview of genetic material: DNA, chromosomes, genomes, homologous chromosomes, sister chromatids, and haploid/diploid.

Chromosomes are made from DNA. Genes are short sections of DNA. Genetically identical cells are produced by a type of cell division called mitosis. In sexual reproduction, a male gamete fuses with a female gamete to produce a new cell....

Given illustrations or partial DNA sequences, students will identify changes in DNA and the significance of these changes.

Get an in-depth look at the importance of DNA with this library of information on nucleic acid structure and function. Understand the structure and function of DNA by exploring topics in the chemical structure of DNA, organization of DNA...

Find out about mitochondrial and chloroplast DNA, and why its inheritance does not follow Mendelian patterns.

In this science project, you will investigate the secrets of your distant past as revealed by your DNA. In order to obtain a sample for DNA analysis, you will scrape a soft swab inside your mouth to collect cheek cells. Based on the...

This video explains how DNA works and what it does, relating it to an instruction manual for building an organism. [4:29] Followed by a short quiz and a list of additional resources to explore.

Discussion in detail of the structure and function of the nucleus and ribosomes of a cell and how they work together in the production of proteins.

A complete, student-paced lesson on genetics and inheritance. Students work their way through illustrations and animated tutorials, and answer review questions along the way. There is a self-checking quiz at the end of the lesson.

Eukaryotic cells have separate DNA from mitochondria and chloroplasts which indicates that they were once primitive cells on their own. This multimedia article includes animations, pictures, video, biographical information, and quiz...

Examples of using DNA for forensic purposes is discussed here, as well as uses to unravel historical puzzles, trace the history of a species and answer health problems.

This lesson focuses on DNA including it's structure,components,and how it goes together to form genomes. It also provides to links to a video and a test.

The scientists and experiments that discovered that DNA is coiled into chromosomes are the topic of this article. Article includes animations, pictures, video, biographical information, and quiz questions that are accessed by clicking on...

At DNA from the Beginning, choose from classical genetics, molecules of genetics, genetic organization and control. Each concept is explained through animation, an image gallery, video interviews, biographies and links.

This interactive lab will enhance learning about DNA by virtually translating a gene.

An explanation of genomes in regards to the amount of DNA compared to the number of chromosomes in different organisms. Additional discussion focuses on how the human genome is different from other species.

This is the homepage of the Austrialian Genome Research Facility. It is dedicated to the sequencing of DNA and understanding genetics.

Get it all straight! The "Tour of the Basics" will help clarify the basic principals of genetics science from DNA, genes, chromosomes, proteins, heredity, and traits.

The sequence of DNA that we inherit from our parents encodes directions for making our cells and giving us specific traits. Robin Ball explains how the secret lies in X chromosome inactivation.

Provides detailed explanation of DNA's structure and function. Includes illustrations.

The interactive activity examines the discoveries of genetics and chromosomal inheritance of Thomas Hunt Morgan.

See how telomeres act as protective "caps" on the tips of eukaryotic chromosomes. Also learn how telomerase extends telomeres.
