Investigate how the genetic code on a DNA strands controls what protein is produced with this collection of animations and 3D models. Explore an interactive 3D model of the double helix, watch an animation of transcription, and see the...

[Free Registration/Login may be required to access all resource tools.] The mRNA, which is transcribed from the DNA in the nucleus, carries the directions for the protein-making process. mRNA tells the ribosome how to create a specific...

Brief text summary of what students learn in the Dragon Genetics II lab along with links to download Student Handouts in PDF and Word formats, and Teacher Preparation Notes in PDF format. Students use paper models to learn transcription...

Learning about transcription and translation can be difficult but this animation helps make the processes less confusing. The animation is interactive and it also covers the overall importance of proteins.

This lesson focuses on how genes, sections of the DNA, are formed including descriptions of transcription and translation. It provides links to a video and a test.

DNA has four letters that must specify the 20 different amino acids that make up proteins. This animation shows how using three DNA letters for one amino acid makes the most sense. [1:07]

Once a gene has been located and transcribed into mRNA, it must first be edited before it can be translated into a protein. This editing process is called splicing it involves removing non-coding regions called "introns", leaving only...

A step-by-step animation shows how introns are removed during RNA splicing.

This site goes through the process from control at DNA to transcription and translation. Some illustrations to help show the process. Links for vocabulary words and other illustrations.

Learn the fundamentals of nucleic acids and how they experience the processes of replication and translation with the series of problems presented here. The correct answers have a brief explanation to reinforce the theories and incorrect...

Interactive resource provides students with an opportunity to work through a problem set over nucleic acids. Correct answers are reinforced with a brief explanation. Incorrect answers are linked to tutorials to help solve the problem.

A series where students see how to submit a nucleotide sequence, compare it to other sequences using blastn, and interpret some of the results.

[Free Registration/Login may be required to access all resource tools.] The DNA sequence contains the instructions to place units called amino acids into a specific order. When these amino acid are assembled in that specific order,...

Try this interactive module from the Brooklyn College to help understand the genetic code and how changes in the code effect the final protein product.

[Free Registration/Login may be required to access all resource tools.] Overview of the central dogma of molecular biology.

Take this interactive quiz over Mendelian and molecular genetics, then review your score and any missed questions at the end.

Animation studio that specializes in medical illustration lets you explore the structure and function of plant cells and animal cells, using videos and interactive graphics with clickable parts that lead to more detail.

These pages are part of a site called Evolution that accompany a textbook by the same name. Mark Ridley is the author. In this section: the universal genetic code provides evidence that life has a common ancestor.
