Hi! This channel is literally the best source to understand the IB Biology topics. I think your explanation is even better than the original IB book that we cover in the lesson. Please keep making videos like this, these help me the most on my exam weeks. Thank you so much!😄
hi! Just want to say you've been a hugeee help when it come to studying for IB your videos are the best out there and I recommend you to all my friends! Thank you so much!
I just checked out your channel yesterday to see if there any videos on unit 7. I'm self-studying it right now with Pearson and Oxford textbooks and Alex Lee's videos, because my school is below average in terms of education and I still need to get high score, so your videos are a great summary of the topic. Thanks a lot for the vids!
Had a question about lagging and leading strands, I find it very difficult to know the primers, any tips? Also, thank you for posting this video! I looked everywhere on RU-vid and no one explains it better than you!
Primers are generally used to start the process of adding complementary bases to an open strand. Because enzymes like DNA polymerase can only attach nucleotides to existing nucleotides, there has to be some nucleotide there to start the process - and this is the purpose of the primer - it sets a nucleotide in pace for DNA polymerase to use. The process of DNA replications uses an RNA primer, but the process of transcription does not need or use a primer because RNA polymerase takes on that role (with the help of other molecules). This is a very generalized answer (missing quite a few details) and a bit beyond the scope of what I discussed in the video, but I hope it helps!
That terminology is part of the HL curriculum. This video is designed to cover the SL part. Unfortunately I do not have the 2024 HL video complete for this section 7.2.
I created them as a tool to be used for learning the content for the first time, but I know that many students also watch them as review. So I guess whatever makes the most sense for you!
Oh ok so if i base my notes mostly on your videos i should be fine? I’m only asking because your videos seem relatively short compared to some other sources.
