she is honestly amazing AS A TEACHER AND AS A PERSON , all you gotta do is just speed up the video to 1.5 and she is a literal life saver before exams. PERFECTION IN LITERAL MEANINGGGG
Honestly, you're a lifesaver! Really good video, keep up the good work. However, I think I found one mistake with the presentation. At 37:20 when you are trying to figure out how many codons can produce Isoleucine, you said two codons(AUC & AUA like you labelled with red in your chart). However, I think there are 3 codons, as you missed AUU, right above AUC. I might be wrong, but I do think that there are 3 codons can produce Isoleucine not only two. Anyways, thanks for the amazing vid and keep up the good work!
me too, i added that in my notes. i think she must have just missed it because if it is an exception, I'm pretty sure she would have mentioned as to why its an exception but ig we just include it
Hi thanks for the video but I have a small question. At 37:44 when asked "how many codons produce isoleucine" you said it was two but in the table pasted in the video, even AUU produces isoleucine right? So shouldn't the correct answer be 3. Thank you once again.
7:19 why is it that the DNA is facing the same direction? You mentioned that DNA has an antiparallel structure, meaning the strands are going in opposite directions, but in this case, I could see the deoxyribose facing the same direction. correct me if I am wrong
Its somehow not convincing in the Meselson experiment, where the DNA with all N14 is replicated from second generation of DNA ( that contains both DNA strand of N14 and N15) if this fact justifies semi-conservative replication. I mean having DNA with all N14 implies that a single strand of N14 in second generation of DNA makes a complementary strand of DNA that is all N14 which sort of seems like a conservative replication.
I don't understand the purpose of the last few parts of the Meselson-Stahl Experiment. Once you have moved the DNA from N15 to N14 Broth and observed that the DNA floats in the middle, isn't semiconservative replication proven already? If it was conservative replication, there would have been two DNA layers, one at the top and one at the bottom. I don't see why this DNA then needs to be moved to N14 broth and another generation of bacteria to be observed.

Totally agreed 👍

yes i noticed this too!

You ROCK!!! THANK YOU. LIFE SAVER, GRADE SAVER, MY SAVER!
YOUR VIDEOS ARE SAVING MY LIFE IN IB BIOLOGYYYYY
Duah Algadi same
Shut the hell up
@@everybodyhateszak thats not very nice
Same
@@everybodyhateszak no u
I love how you explain everything so well and simplify it to make it easier to comprehend, thank you so muchhh
You are amazing. You're not getting enuf cred for your work but keep it up!!!
god bless this woman.
once again another great video... thank you very very much. We really appreciate your work globally as ib students:)

Got a 6 in biology all thanks to you ❤️
6:52 not the holy-canoly 😭 😭

yeah a small mistake
i love you so muchh lifesaver ACTUALLY
is this for HL as well as SL?

You are an excellent Teacher!!! It's so refreshing to see how you simply the concepts and make them easy to grasp. Thank you. Keep up the great work!
