On my aqa spec it says that we do need to know about the 3 prime and 5 prime, which I struggle with understanding. Would you be able to do a video explaining since they are really helpful
The aqa as bio playlist is missing a lotttt of videos, I saw some in my recommended and assumed they perhaps weren't on the paper anymore but it's carbs etc and a lot more topics which are super important. Could they be added?

thanks, very clear video. could have went into more detail with messelson and stahls experiment as now the exam board want us to know about it. nevertheless, the video was well explained :)
