DNA Transcription (Basic Detail)
A double helix looks similar to a curled zipper. Viewers see transcription, which appears similar to unzipping the DNA. The basic level of detail works well as an introduction to transcription, RNA, and proteins.

DNA
The picture of the DNA double helix provides a logical start to describing how the base pairs match up and how the order codes for a chain of protein molecules. Three billion of these base pairs code for any protein present in your body....

Transcription and Translation
AAG-CCT-GAA: Can somebody translate this for me? A video demonstrates how transcribing and translating DNA is similar to reading a cookbook to make a meal. Scholars walk through the steps of transcription, converting genes to mRNA. Video...
Crash Course
DNA, Hot Pockets, and the Longest Word Ever
Show learners how DNA transcription works with a video that details the step-by-step instructions required to copy genes, and how cells follow those instructions, via translation, to produce proteins and enzymes that help build further...

AZT Blocks Reverse Transcriptase
AZT, developed in the 1960s to treat cancer, actually treats HIV as well. Viewers observe how AZT blocks the reverse transcriptase of HIV. Then they see what happens when the virus mutates to be immune to AZT.
