I’m from Singapore and I’m doing my A levels this year! Your videos really help me understand and internalise the concepts/processes quicker. Thank you so much for explaining them concisely 🙏❤️
This was so helpful! I've recently been studying mutations and natural selection(section 9) and understanding codons and anticodons seems to play quite a big part in the exam questions!
Sorry, just a question. For the rRNA, if the 30S subunit and 50S subunit combine together shouldnt they form 80S ribosomes which are found in eukaryotic cells? (Not 70S as they are found in prokaryotic).
Do we need the information on rRNA and the difference between DNA and RNA in this section of the spec for AQA, or should these parts only be used for topic 2?
thank you for all the effort you put into teaching us! im just wondering if are all these videos still up to date with the spec as its been a few years since posting? thanks!
Hello! I wanted to mention that you use the chapter function to separate your videos, but tRNA is merged in with the mRNA section, making it a little more difficult to jump to that section specifically for quick revision in a pinch
Great video thank you!!! I was wondering- when do you reference the three bases as a triplet and when do you call them a codon? I've got a bit confused when writing exam questions
Hello, Technically, a codon is 3 bases on mRNA that code for an amino acids. DNA has a triplet of bases which are transcribed into mRNA. So it should be codons for mRNA abs triplets of bases for DNA. Hope that helps.

Thank you so much for all you hard work
Aww thank you 😊☺

ah wow, hello! I'd love to visit Singapore.
I'm so pleased you are finding my videos helpful!!!
Really a great, teacher.....
I ever seen....
Love from India 🇮🇳
Thank you 😊

So glad it has helped with what you're currently learning 😁😁
No DISLIKES!!!
My teacher didn't have a powerpoint for this lesson,thank you so much for making one this was really helpful:)
So glad it helped you !!! 😀
So butifule. Iam from egypt and learnd good information. And love you

Really happy to hear its helped you learn for your studies 😊
I see u with that remix at the end
haha my theme tune!
honestly the first 6 seconds sounds like horse running

Thank you for these videos I feel I really understand. However I do get frustrated because I have no idea how to answer exam questions.
Do we need the information on rRNA and the difference between DNA and RNA in this section of the spec for AQA, or should these parts only be used for topic 2?
is rRna the same as preRNA? also thank you for your videos! I struggle learning out of a textbook and your videos are so helpful!
Hello
No they are different.
rRNA is what makes up ribosomes.
pre-mRNA is messenger RNA before it has had its introns spliced out.
Hope that helps ☺
thank you for all the effort you put into teaching us! im just wondering if are all these videos still up to date with the spec as its been a few years since posting? thanks!
hey, yeah they are. The AQA spec hasn't changed since 2015

Thanks for the info! Sorry about that!
Do we have to know the 3 different types of RNA even if it isn’t included in the specification?
hey it comes up in topic 4 for aqa
Do we need to know exactly how tRNA enters the ribosome to attach to the amino acids?
No, that's not needed
@@MissEstruchBiology thank you!
you are quite literally the reason a level biology isn't hell like the other two sciences
ahhh so pleased it's made you enjoy Biology more 😁

is mRNA tRNA and rRNA on the aqa specification?
hello,
yes all three are in topic 1, biological molecules
Do we need to know 3 types of RNA for AQA?
yeah you do
Good evening Ma'am,
Just wondering, is this from topic 1 or 4 because it appears in both playlists?
Ty
do we need to know MRNA , TRNA AND RRNA and what they do?
Hello, yes it's a small part of the specification in topic 1 and then mRNA and tRNA come up in more detail in topic 4 for protein synthesis 😊
Hopefully this pops up in my exam
Good luck for the exam!
@@MissEstruchBiology thanks miss it popped up and got a B
Hi, i love your videos :) are the tRNA structures specific to only 3 bases or can they change?
yes, there are multiple different tRNA molecules each with different antibodies, complementary to the codons on mRNA.
@@MissEstruchBiology thank you 💕
I was just wondering would the 3 differences of structures between mrna and trna be clover leav vs linear and one gene vs multiple genes?
Hello,
this sounds more like a comparison of DNA and mRNA.
cheers
