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...

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...

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...

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,...

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 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.

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...

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...

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...

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...

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

Students, in groups, research, analyze and synthesize information on genetic diseases. After watching a video on genetics, groups perform research on a variety of genetic diseases and present their findings to the class.

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.

Ninth graders complete a monohybrid cross and a dihybrid cross. In this biology lesson, 9th graders predict the traits of offspring using the Punnett square. They differentiate recessive and dominant genes.
