Students define the term "evolution" and relate it to species adaptation, supporting their ideas with examples. They locate, correctly cite, and briefly review two Web sites with information on finches commonly found in their state or count

Students explore the field of genetics. They examine four basic traits. Students demonstrate their knowledge of phenotype and genotype by charting their personal traits. Students compelte a Meiosis chart. From the chart results,...

Students simulate the steps involved in creating a DNA fingerprint by the RFLP technique. They analyze RFLP patterns to determine the parentage of a missing baby.

Students investigate variation in the beta globin gene by identifying base changes that do and do not alter function, and by using several Internet-based resources to consider the significance in different environments of the base...

High schoolers describe some aspects of known genetic defects on the human neurological condition. They participate in a variety of exercises including drawings, games, and analogies.

Students use research to see how eight pairs of triplets are equivalent to part of a gene and control a part of heredity. They also understand how red blood corpuscles manufacture normal hemoglobin.

Students explore and explain how mutations in the DNA sequence of a gene may be silent or result in phenotypic change in an organism and in its offspring. They analyze how evolution and biodiversity are the result of genetic changes that...

Students in pairs, select and view proteins from the Protein Data Bank. After downloading the tutorial and instructions, they identify the protein's structures and primary biological functions. Then, students present their findings to...

In this genetics quiz worksheet, students complete a set of 10 multiple choice questions covering various concepts of genetics. A reference web site is given for additional resources.

Flip this interactive OLogy card to find questions and answers, fast facts, and other bite-size pieces of information to help you understand DNA bases A, T, G, and C.

Instructional module focusing on the physical structure of DNA. Discussion incorporates the description of the nucleotides, base pairs, and the double helix shape of a DNA molecule. Site also includes an interactive practice quiz and...

A good Access Excellence site with an introduction to the processes of transcription and translation, leading to a student modeling activity.

[Free Registration/Login may be required to access all resource tools.] Students can watch a video, read some informational text and key vocabulary terms, and answer review questions about the structure of DNA.

Learn about base pairing in DNA, and how the ratios of adenine to thymine and guanine to cytosine are equal. [0:47]

[Free Registration/Login may be required to access all resource tools.] Module describes how DNA's structure and function was discovered while summarizing the process of DNA replication. This activity also explains Chargaff's rules and...

[Free Registration/Login may be required to access all resource tools.] DNA is located in the nucleus. Proteins are made on ribosomes in the cytoplasm. Remember that information in a gene is converted into mRNA, which carries the...

[Free Registration/Login may be required to access all resource tools.] DNA must replicate (copy) itself so that each resulting cell after mitosis and cell division has the same DNA as the parent cell. DNA replication occurs during the S...

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

Discover the structure and function of DNA.

This is a very informative site on DNA mutations. There is estensive information and helpful diagrams.

Access Excellence provides an excellent graphic showing the structure of the DNA molecule and its components.

This site is provided for by DNA Interactive. The genome is the entire endowment of genetic information. It is the "Book of life," on an organism. This site demonstrates the methods used to map and sequence the human genome and to...

In story form, this complete site examines what DNA is, the structure of DNA, genes, and replication. For clarity purposes, the text is supplemented with drawings.

This is a project about the "molecular alphabet" of DNA. With just four "letters," it manages to keep track of the plan for an entire person, and keep a complete copy in nearly every cell. This project will help you start learning this...
