A Level Biology Revision "Cell Fractionation"

You can find all my A Level Biology videos fully indexed at https://www.freesciencelessons.co.uk/... In this video, we look at how organelles are separated by cell fractionation. First we look at the roles of a homogeniser and buffer. We then look at the relative sizes of the different organelles. Finally, we explore how the organelles are fractionated by ultracentrifugation.
