Before a cell replicates, its DNA must replicate. Take advantage of a hands-on guided lesson to teach budding scientists how this happens. Using a set of nucleotide cards, learners become the DNA and work to create matching strands...

Students examine how traits are passed to offspring.  In this genetic reproduction lesson students develop a model of dna and learn about its structure, replication and function.

Reward biology learners for working hard in their mitosis lesson with a sweet snack at the end! They begin by twisting apart creme-filled cookies and using the icing as a cytoplasm. Colored candy sprinkles make up chromosome pairs,...

Parts of the cell as well as genetic material begin this presentation.  As the slides continue, there are explanations of the main terms used in genetics.  The structure of genetic material, chromosomes, and replication are...

Three steps are needed to extract DNA from learners' inner cheek cells. The procedure and reasons for each step are explained. As enzymes work on the cells, a series of questions are answered regarding the structure of the DNA molecule....

Students explore genetics, chromosomes and DNA.  In this genetics lesson students design a chromosome and identify a family tree through genetics. 

Create your own karyotypes with clay in a kinesthetic genome activity. This tactile experience was created for visually impaired pupils, but can be used for all hands-on learners who are beginning to study chromosomes. The preparation...

For this DNA: structure and replication worksheet, learners fill in the blanks about the structure of DNA and replication of DNA. Students sketch several diagrams of DNA at different stages.

Students review the structure and function of DNA, genes, and chromosomes and are engaged by a demonstration illustrating the relative size of DNA, genes and chromosomes. They also describe through analogy and model the structure and...

The question of the structure and function of DNA being the same in almost all organisms is raised here. You will find this PowerPoint a great summary of the building blocks and replication of DNA. The differences between...

Advanced biology masters take a close look at DNA and the scientists who contributed to our understanding of this complex and powerful molecule. They answer 21 questions about DNA structure, replication, and repair. This can be used as a...

Are you a mutant? Learn about multiple types of mutations with a presentation to discover the answer. Both genes and chromosomes mutate at various points in their life cycles. Slides describe each type and the resulting impact on...

These two pages cover the gamut of topics regarding reproduction and DNA replication. Structures, processes, functions, and reasons for them are tested here. The questions are mostly multiple choice, but there are also a few...

This mitosis worksheet targets AP-level biology courses. Learners identify the roles of kinase, cyclin, and CDKs, as well as describing external signals for growth. Large and colorful diagrams are displayed within the worksheet for...

Young biologists define reproduction vocabulary terms, answer critical-thinking questions, label a diagram of the human life cycle, and complete a chart comparing mitosis to meiosis. This is a well-balanced worksheet. Even though it...

High schoolers use analogies to show the relationships among cell, nucleus, genes, chromosome, ribosome, replication, mitosis, transcription, translation, DNA, RNA, amino acids and proteins, genotype, phenotype, and genetics vs....

Based on current scientific knowledge, all cells come from preexisting cells. Scholars learn about cell division, cell replication, mitosis, meiosis, and more with a PowerPoint. It describes the differences between prokaryotes and...

Uncover the basics of DNA structure through exploration activities. Collaborative groups build DNA models and recreate the process of replication. Then, using plant cells such as peas or strawberries, they extract a DNA sample.

In this DNA replication worksheet, students review the steps that take place for DNA replication. This worksheet has 9 fill in the blank questions.

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...

The New York Regents High School Examinations are comprehensive and include various question formats, including multiple choice and graph analysis. This particular version, the 2008 Living Environment exam, surveys a variety of topics....

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...
