haha well this is an over view and Im sure in lessons you get. a chance to practice questions etc.
BUT I am glad you found it helpful
yeah and if you put it on 1.25 speed. only takes 30 and still easy to understand
gcse biology is real biology, then u switch to a level biology and u start to learn chemistry 😭😭😭😭😭
Yes now, need this for my mock! Thanks!!!
Perfect timing! I hope it helps with your revision 😁
Did u get the grades?
I'm trying to self teach A-Level bio as an adult, thank you for this ❤
you're so welcome !!! Good luck
do u set urself exams to do
@@josephxjoestar Hi, im self teaching too and we dont set ourselves exams, we sign up for exams at the end of the year at an exam center, and the exams will be at the same time and date as everyone else doing the A-Level we signed up for e.g. I'm doing my biology a level with AQA and my exam will be at 1pm at 5/06/2024, the same time as everyone else doing their biology a level with AQA.
here I am a week before my exam even thought this shouldn't be the case. covered the whole topic. your awesome!
Hope it helps!!!
how did you do
Thank you! Just passed my GCSEs and I am studying ahead of time now, you are unfathomably fantastic! Also nice necklace, nothing to do with anything - I just think it is cool.
you probably realised what a good decision youu made. i was hestiant during the holidays altho i had planned to do so. i was procrastinating. then i went abroad i did some work in last couple days but ig i benefitted abit but good job
I have a test tomorrow on this and you are sooo helpful. I didnt feel prepared until i watched your video! ❤
im doing a level 3 diploma in medical science and this video has practically saved me right before my exam. thank you so much for being straight to the point with this topic! (unlike my class teacher)

I'm so glad!
So helpful, thank you! Having the whole topic in one video is so great for a recap and refresh :)

Just watched the video while I was having lunch (and watched the rest of the video standing to help with digestion haha)
Thank you so much for doing this
🤣🤣 haha love it. Amazing multitasking
@@MissEstruchBiology yes XD a relaxing supplementary revision session
So do all these whole topic videos reach all the specification points. Hoping this alongside my detailed book note flashcards is sufficient. Thanks
This is really helpful ❤❤
I'm so glad!
Omg this is soo helpful!!!! Will you be doing this for the whole topic ready for the exams this year?
Yes! I will do one for will 8 topics. So glad you found it helpful 😁😁
Love you miss 😊
😄😄 Really hope this helps boost your revision and grades 📚📚📚
Truly a great video Miss, so helpful with this topic. IBut I just wanted to ask, would it be possible if you could possibly edit the video so that the quality is better? The maximum quality I could get to is 360p and it sort of affects how I can concentrate.
Thank you for your efforts Miss
Hey Justin,
So glad you find it helpful!!
That's really helpful feedback. I am just exporting my next video at 1080p this time!! Fingers crossed that works and is better for you.
@@MissEstruchBiology You are actually a Godsend! Thank you so much!!
really good video thanks! will you do more videos like these with the other topics?
Yes! Will being doing one for all 8 topics
@@MissEstruchBiology thanks so much 😊
hi miss, you know for the carbohydrates in the disaccharides when you do the equation for each, do you have to specifically know if it’s alpha or beta glucose being used??
hello. No you don't have to for AQA
@@MissEstruchBiology thanks miss happy new year! I have my mocks next week (Y12) and im being tested on topics 1 and 2
@@izzy7338 omg same lol
Thankyouuuu!!!
You're welcome 😊 Hope it was helpful
Do these lessons also work for CIE A Level?
Hi miss Estruch, thank you for this video, can I ask where the topic 4 video is on dna, genes and protein synthesis?
Coming next week 😁😁
great vid miss
thank you!
very very helpful!! this question might sound dumb but, are the a level notes sold as soft copy or shipped as hard copy?
Hey, all my products are digital
Thank you so much I was wondering if you did topic 2 pls
That's coming this Monday! Hit the notifications symbol so you don't miss it ☺️
Hey, thanks for the video, really helpful! Had a quick question though. At about 30:33 you said that the nucleotides are joined together by DNA polymerase to form phosphodiester bonds. However, I thought that the bonds between nucleotides are hydrogen bonds and those between the pentose sugar and the phosphate group in DNA. Could you confirm that?
hello, the bonds between bases on different strands hydrogen bonds, not between nucleotides
Is the lock and key model a simpler version of the induced fit model, or are they completely different things?
Hey, they are different models.
how much more detail is there to know in terms of dan replication, like 3", 5', Okazaki fragments and stuff
thanks
For AQA you don't need to know that. I have a separate DNA replication video as exactly the standard for AQA that will help
does anyone know if this content majorly differs from the OCR alevel, because i cant find a decent video for OCR
this topic is relatively similar. BioRach is amazing foe OCR though
Can i use the sample for edexcel?
Hello, may I ask how you would revise for a level biology and how I can ensure that I can achieve A/A* in a level biology?
Thank you
hey email me at missestruch@gmail.com and I'll send you a Full list of ideas and recommendations of resources
bruh ur the goat for real
thank you!
My exam is a month away and I’m really worried i hope it’ll be easy
low-key tryna self teach myself some of the content before i do this at college 😮
22:19 shouldn't the graph on the right decrease as there is less substrate to react so the reaction is not constant?
hey, that would be if the x axis was time. This isn't a change over duration of a reaction. Its showing the rate at set substrate concentrations. Hope that helps
@@MissEstruchBiology yep, cheers
hi miss, will all of these summary videos be up in time for this years a levels?
yes! I'm doing 1 per week, third one comes out tomorrow
so all 8 should be uploaded before the end of March
Does reducing sugar test only test for disaccharides? I don't understand why acid is added to hydrolyse monsaccharides in the test for non-reducing but no acid is added in the test for reducing.
Reducing sugars tests for all mono and disaccharides, except sucrose. Sucrose is the only one that is non-reducing because the chemical group that is able to reduce is involved in the glycosidic bond. Thats why you have to hydrolyse the molecule, and then it works.
Thank you so much for your reply, that’s really helpful! I have a topic test tomorrow and your videos have been a massive help.
@@daisylawrence7447 how did you do
Mrs Estruch, are these whole topic videos all the theory you need for A level bio? So aside from exam technique and mark schemes, etc do these whole topic vids cover all content needed for the A*
Yes, but my individual videos on each topic give it in more thorough detail for a better understanding
Hey I’m new to a level and do not know how the specification works, at 1:59 you said that glucose is an example of a monomer but on the spec it says monosaccharides, are they the same thing
Yeah
Monosaccharides are single sugar units. Examples of monosaccharides are glucose, fructose and galactose.
Ty miss 👍🏽👍🏽
You're so welcome. Really hope this helps streamline your revision 📚
TYSM GURLLLLLL XXX
24:27 isn’t it iodine in potassium iodide, if not, you won’t get the mark. Because I’ve seen that in mark schemes
is that really all we need to know for inorganic ions or is there more btw this vid is so helpful
so pleased it was helpful! That's it! You learn the roles applied to examples throughout the A level in other units
Watching it 5 mins before exam😢😢😢
eeek good luck
hello miss can you make a video on inorganic ions please.❤
I'm doing Edexcel B can I still use this video? :( There aren't many videos out there for my spec :/
it doesn't match up exactly for Edexcel, but there will be some overlap. You'll need to check it against your spec carefully
Is this suitable for AQA and OCR please?
yes for AQA, but with OCR check the spec to make sure :)
life saver ,
😁😁😁
Can OCR a level students use this ?
yeah, BUT check against your spec as it isn't identical information
where was the mention of the 5' and 3' end of DNA? Really good video but still some gaps!!
That level of deatil is not needed for AQA. Glad the videos helped :)

Penalty for Argentina
I agree
@@IsmailKhan-oe1rt have some bepsi
no ronaldo
im doing ocr, is the content still the same?
It's similar but not identical. I have actually just released my OCR notes! missestruch.co.uk/product/a-level-ocr-a-notes-full-set-topics-1-6/
Not the hero we deserved but needed
awww thank you 😊
yay
Hope it helps boost your revision motivation and grades 😁📚

So no one is going to question the random breathing at 16:30...
haha I think that's my cat. She features a lot in my videos, but in the talking head videos of mine you see her. She likes to sit right by my computer when I record.
