With paper DNA patterns, budding biologists model translation and base-pair substitution within sequences. Through these activities, they examine how mutations can result in genetic disorders. The modeling that occurs is an enlightening...

Enzymes proofread DNA, reducing the error rate to one in one billion base pairs. Learn about the important process and so much more with the help of a presentation. It opens with the history of DNA and the major scientific contributions...

A pinch of adenine, a dash of thymine and ta-da, you have life! Well, it's not quite that simple, but through this series of activities and experiments young scientists learn about the structure of DNA and how it contains the recipe...

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...

An excellent review of the very specific stages of mitosis, the detailed slides start with explanations of the directionality of DNA and then develop the concept of daughter strands. The intricate diagrams are intended for experienced...

Why do the bases in DNA pair up the way they do? Unravel the mystery of the double helix in a virtual lab. Young scientists follow in the footsteps of Watson and Crick to determine the free energy associated with DNA base pair binding....

The many slides and images in this PowerPoint are clear and relevant to the detailed content covering the details of DNA structure, replication, cell differentiation, and mutation on an advanced level. The slideshow summarizes all of the...

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

High schoolers see DNA as a physical building block of organisms and comprehend the basic structure of DNA and the specific components in its structure. They can explain the specific nature of base-pair matching in DNA and that DNA bases...

After viewing this presentation, students create a complete set of notes to support their learning of DNA replication. Each slide has information on a step in DNA synthesis process. The slides focus primarily on the processes rather than...

Future geneticists use base pairing rules to build DNA and RNA polypeptide strands, and then explain both transcription and translation. Although the chains themselves are a little blurry, there is plenty of room in them for learners to...

Transcription means a written copy but how can DNA write a message? The video explains transcription and translation as they relate to DNA and RNA. Then in the interactive, scholars practice base pairing and answer analysis...

Learners create models of DNA and RNA using string and beads. They use beads representing the four nitrogenous bases of DNA to create a portion of a strand of DNA, and it's corresponding RNA. Then, students examine how many of their...

One of the first models of DNA appeared to be a triple helix. Young scientists learn about the many scientists who worked to find the shape of DNA. They observe multiple models, tests, and experiments to understand the conclusions. An...

Here is a cut and paste activity worksheet designed for older students. They fill in the blank with information about the composition of DNA, then create a DNA strand with its complimentary nucleotide chain.

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.

Students study DNA decoding and protein synthesis. They use the amino acid table to translate DNA, break DNA strands into three nucleotide codes, and translate nucleotides into amino acid protein codes. They research the importance of...

Students explore DNA. They work in groups and mix prepared detergent/ salt solution, meat tenderizer solution, Fleischman's yeast and water to extract DNA from yeast. Observations are recorded.

DNA molecules hold the secrets that make us unique. The fourth of 12 lessons explores the structure of DNA by building candy models. After building the models, young scientists break their models to begin the process of DNA replication....

In this science worksheet, students read about cells, chromosomes, and genes. Students order the following items from largest to smallest: cells, chromosomes, DNA, genes, and bases.

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...

Students build DNA strands and practice base pairing rules using an interactive website in this technology-based lesson plan for a high school science class. This lesson plan includes links to the interactive website, a worksheet, and a...

In this biology worksheet, students review and answer different questions based upon the molecules of DNA and RNA. They look at the specific protein order of the DNA strand and its synthesis.
