This unit includes resources, such as slideshows, worksheets, activities, and labs, on DNA for high school biology students.

This unit is part of the Developing Biology course.


Slideshow: DNA

by Robert Lucas
This resource is a PowerPoint presentation on DNA for high school biology. Topics covered include: Chargaff, base pairs, Franklin, Watson, Crick, nucleotides, purines, pyrimidines, replication, RNA, transcription, mRNA, tRNA, codon, anticodon, rRNA, and translation. Slide #45 has a particular nice animation of the translation process.

This resource is part of the Developing Biology course which contains units on Microscopes; Biochemistry; Cells; Cellular Transport; DNA; Photosynthesis and Respiration; Mitosis and Meiosis; Genetics; and Evolution.

CSI: Protein Synthesis

by Robert Lucas
The year is 2023 and someone has robbed a casino in Las Vegas, and DNA has been recovered. Students are provided with a sequence from the DNA and a key telling which amino acids code for which physical characteristics. They decode the DNA into mRNA, then into amino acids, and then into physical characteristics. Finally, they draw a sketch. This is a lot of fun, but I'm afraid it gives the impression that genes map more directly to phenotypes than they actually do (as with the God gene, the Alzheimers gene, etc). What do others think? Can that be minimized?

This resource presents simulated data from Chargraff's experiments, which showed the nucleotides A and T showed up in similar proportions and that C and G were in similar proportions. Students graph the data and then try to draw conclusions.

DNA Replication

by Janet Pinto

DNA replication animation in real time. It's amazing to think that millions of your DNA containing cells are doing this in your body right now. Remember, this is how fast DNA replicates in real time!
