The above video provides a slightly unorthodox view of genetics, molecular genetics, and the latter's central dogma.

The above video provides some different ways of visualizing the central dogma of molecular genetics: Replication, Transcription, and Translation.

The above video is a quick consideration basically of why, metaphorically, we use the terms "transcription" and "translation" to describe these basic concepts of molecular genetics.

A simple, not very chemical introduction to what DNA is all about is provided in this above video, though beware the poetic license with the shapes of proteins.

The above video is literally a sketchy presentation but makes all the right points.

James Watson, the co-father of base pairing explains base pairing.

A lot said, very quickly in the above video, which isn't necessarily a bad thing, but alas the jokes really are…

Computer animation of leading and lagging strand synthesis.

A very silly song, but nonetheless fun.

A cartoon illustration of homologous recombination as it occurs during meiosis, a.k.a., crossing over, is shown in the above video.

The above video is a quick run through of the words associated with the molecular genetics concept of translation.

The above video is a very short, very basic introduction to DNA damage caused by radiation.

The above video is a brief as well as basic discussion of the diversity of origins of genetic variation in individuals

The above video covers the subject of mutations the subject with an appropriate level of detail.

The above video provides a somewhat in-depth discussion of genetic variation in individuals as well as its prevalence in populations.

The above video provides a simple, straightforward, and reasonably well done introduction to the question of just what is a gene.
