The Structure of DNA | Betsy Skrip, Sera Thornton
An exploration of the structure of deoxyribonucleic acid, or DNA.
This video was created for MITx 7.28.1x Molecular Biology: DNA Replication & Repair, offered on edX.
DNA / Chromatin
Introduction to Epigenetics (for the Boston Museum of Science) | Digizyme
This animation explains how environmental conditions can influence the expression genes. We begin with a simplified view of gene transcription, mRNA synthesis and translation of the corresponding protein. We also observe how epigenetic ‘tags’ (chemical modifications to the DNA) can alter whether or not a gene is expressed.

This animation depicts the proces of DNA recombination. The DNA plasmid is first digested with the restriction endonuclease enzyme ecoRI. Then, a piece of DNA encoding a gene is inserted into the plasmid by DNA ligase.

This animation shows the different levels of chromatin packing – starting with wrapping of DNA around histone octamers and nucleosome assembly, all the way to chromosome condensation during mitosis.
