IB Biology Topics 7.2 & 7.3 (HL): Transcription, Gene Expression, and Translation

This video begins with an in-depth examination of the process of transcription, followed by the components of immature RNA and how they undergo post-transcriptional modification. The regulation of transcription in eukaryotes and prokaryotes is then discussed, before the review of nucleosomes and how they are involved in epigenetics. The important process of translation is then covered and the video concludes by discussing the structural levels of the resulting proteins.

you're a lifesaver omg, your videos are so much better for understanding <3

its such a shame that translation was not included, otherwise a very helpful video for understanding transcription!

oh whoa you've got a nice voice! this is the first time i've focused on anything in 2 weeks. thanks!

Very good video! You make hard concepts easy to understand :) thank you

for the rna polymerase part does it use helicase to separate the 2 strands?
