DNA and RNA - Part 2
Viewers explore the structures of RNA and DNA and then learn how DNA replicates itself. The narrator explains the central dogma, showing how DNA is eventually translated into proteins, before briefly discussing genetic engineering.

DNA Structure
DNA carries the code for all living organisms, yet it is made up of only four building blocks. The video explains the structure of DNA down to the nucleotides. It provides the relationships between thymine, cytosine, adenine, and guanine.

What is Epigenetics?
Epigenetics has more to do with external influences than with our genetic code. Environmental factors can cause different genes to become more or less active in individuals. Watch an informative video to discover how this phenomenon works.
