DNA and Genes

So often, genetics worksheets focus on alleles and heredity. Here is one that focuses on the steps of the gene expression process. After reading a textbook chapter or listening to your lecture, AP biology buffs write short answers to...

Adaptations must be made as environments change. This fabulous presentation features Icelandic icefish, a transparent, scaleless specimen that even has colorless blood. Genetics and adaptations concepts are explored as scientists study...

Does the human body evolve as quickly as human culture? With a stellar 15-minute video, explore the trait of lactose intolerance. Only about 1/3 of human adults seem to still have the enzyme lactase and therefore, the ability to digest...

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...

When DNA relaxes and unwinds after a long day, it literally unwinds. The presentation includes DNA, DNA replication, genes, multiple experiments that helped us understand DNA, the structure of DNA, and transcription. This is the ninth...

There are six boxes on this genetics worksheet. In one, learners draw and label the DNA molecule. In another, they compare pre-mRNA to mRNA. Other boxes require definitions, labeling, and explaining relationships. 

A five-star arrangement of slides awaits your biology class. It progressively steps viewers through the process of protein synthesis within the eukaryotic cell. Colorful representations of the DNA molecule, important enzymes, introns,...

How is DNA structured? Composed of deoxyribose, phosphate, and bases, DNA seems so simple, yet it determines so much of who we are. Give your class a better understanding of their genetic makeup with this video. Part two of two.

Do you know how many chromosomes humans have? Do you know how many of those chromosomes we share with the chimpanzee? A perfect introduction to DNA for your middle schoolers, this video uses a ton of visuals to clearly illustrate the...

How do changes in DNA affect an organism? Scholars explore chromosomes, genes, DNA, and mutations by modeling the DNA of a strawberry. They build a DNA model, then manipulate it to show how changing the genes transforms the strawberry...
