Can you identify mutations just by viewing DNA sequences? Scholars apply prior knowledge of DNA sequences to do just that in an engaging activity. They transcribe and translate genes, thus identifying the locations of mutations. Then,...

A red delicious apple tree with a simple mutation means we now benefit from the existence of golden delicious apples. Learn how simple mutations change genetic information in DNA sequences. Using biographies, videos, and animations,...

In the deserts of Arizona and New Mexico, some tiny creatures show just how quickly natural selection can turn a mutation into an advantageous adaptation. Watch a video about rock pocket mice, who show that one small change can make all...

Does natural light damage or repair DNA? Learn the answer discover the scientists who researched the topic with an online interactive. Scholars read through an online animation presenting the content at their own pace. Then, they read...

More than 90 percent of humans' DNA doesn't code for anything! Scholars watch a presentation as they answer questions relating to gene mutations. They read details, watch videos, and view animations supporting the concepts. The questions...

Can evolution repeat itself? Scholars analyze amino acid data in two separate populations of mice. They learn that evolution repeats itself, but natural selection prefers some mutations over others in different environments. Analysis...

While many mutations are neutral, those that appear advantageous increase in frequency in a population. Scholars use illustrations to make predictions about populations of mice. They follow it up with a video to confirm or refute their...

Very few universities still offer a master's degree in the ecology of grasses, but that was the degree that led George Wells Beadle to an interest in genetics and later a Nobel Prize. Scholars learn about the discoveries of Dr. Beadle...

Have you ever been so tired you missed a major announcement? Eric Wieschaus woke to a call explaining he won the Nobel Prize, but he thought it was just a dream until Christiane Nusslein-Volhard, a co-winner, explained it to him later...

This exam covers every topic in a typical first-year biology course. A wide variety of question styles gives high schoolers every opportunity to show what they know. Why start from scratch when a comprehensive final exam is easily...

Emerging ecologists need a full understanding of life, from the inner workings of a cell to the complex relationships among organisms. This examination is meant to assess high schoolers after an entire year of courses on the living...

Environmental science enthusiasts show what they know at the end of the year by taking this full-fledged final exam. They answer multiple-choice, graph interpretation, and essay-analysis questions, 73 of them in all. Topics range from...

The 2005 version of the Regents High School Examination in ecology is as comprehensive as previous years' exams. It consists of 40 multiple-choice questions on topics ranging from the structure of DNA to interactions within an ecosystem....

The living environment, from the interior of a cell to the complex relationships among populations, is queried in this final examination. Learners examine air pollution maps, cell diagrams, population graphs, and drawings of cells. They...

Students review terms related to DNA structure and function. They complete a variety of worksheets in small groups or in pairs reflecting the unit's concepts regarding DNA. They submit their worksheets for grading.

For this environmental worksheet, students complete a series of multiple-choice and short-answer questions on cell types, cell division, chromosomes, and plant species.

In this environment worksheet, young scholars complete a series of multiple-choice and short-answer questions on genetics, populations, and cell structure.

Cells demonstrate a life cycle like other living things, but what if death was no longer part of the cycle? Learn about the important balance requiring death to continue functioning. An online interactive introduces a group of scientists...

Everything evolved from a common ancestor, but how did modern plants and animals develop so many more genes? Scholars use an online interactive to learn about the process. They begin to understand common genes with an animation, multiple...

Biotechnology changes lives every day, but how did it all start? Learn about Cohen and Boyer's technique for recombinant DNA and the founding of this new scientific study. Then, scholars use the online interactive to discover how Hanahan...

Mario Capecchi requested funding for a new procedure targeting genes and was rejected. Four years later, after he proved it worked, the NIH apologized and funded his research. Use an online interactive to learn about his research and the...

Seventh graders explore general structure of and natural changes that occur in DNA strands, and discuss concept of genetic engineering by creating small portion of strawberry chromosome with three genes, modeling naturally occurring...

Students, in groups, complete a worksheet on DNA transcription and translation. They determine codons for particular amino acids. They attempt to introduce mutations to determine what will happen to the DNA sequence.
