RNA Nucleic Acid Structure & Function:A-level. Do you know the differences between mRNA, tRNA &rRNA?

RNA is a nucleotide monomer that joins via condensation reactions to form a polynucleotide held in place by phosphodiester bonds. Learn the differences in structure and function of tRNA, mRNA and rRNA

Thank you so much for all you hard work <3

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 🙏❤️

[AdityaDwivedi-lqrr]

Really a great,
I ever seen....
Love from India 🇮🇳

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!

My teacher didn't have a powerpoint for this lesson, thank you so much for making one this was really helpful:)

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).

[lolwhat]

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!

[ImranAwan-ns]

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?

[abdosalahdela]

So butifule. Iam from egypt and learnd good information. And love you
. 💙

[abbey]

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!

[jenk]

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

[tylerwareham]

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.

[anasmohamed]

Do we have to know the 3 different types of RNA even if it isn’t included in the specification?

[x_chips]

is mRNA tRNA and rRNA on the aqa specification?

[harrietrose]

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

Do we need to know 3 types of RNA for AQA?

[andrejameske]

you are quite literally the reason a level biology isn't hell like the other two sciences

Good evening Ma'am,
Just wondering, is this from topic 1 or 4 because it appears in both playlists?

[najmallayl]

Do we need to know exactly how tRNA enters the ribosome to attach to the amino acids?
