The 'whole of the topic in … minutes' videos DO NOT comprehensively cover everything you need to know for your exams. It would be impossible to include 2 years of teaching in 1 hour. These should NOT be your only source of revision • Do the 'whole topic in... My exam predictions are just GUESSES!! I don't have any insider knowledge just years of looking at exam papers.

Meeeee
your videos are literally amazing, you give me hope to keep revising!!!! thank you
ok, its an awesome video but maybe for future videos try to edit the parts where you are writer a little faster as I found my self just sitting there waiting for you to finish writing it which made me get really bored. And I also had to speed up the video. It's an awesome video though. really helpful.

Hi, could you say that the sex gametes are ovaries and testes rather than eggs and sperm in answer ?
no, they are not the gametes, but rather were they are produced
Science and Maths by Primrose Kitten Oh I see, thanks!
The hardest thing I’ve heard in my entire life
@@thecn83 hope I do :)
@@thecn83 you stuck on science? Cause science and maths are my least fav subjects and their really hard
@@thecn83 ahhh lol lucky you then I like art and technology :)
@@thecn83 loool what yr u in?
@@thecn83 aww I’m in 9 btw, this is really personal but u female or male or other?
Just wondering if the genotype ‘ff’ means that the person has cystic fibrosis? It says ‘ff’ in the video is normal but my revision guide says ‘ff’ is an affected ( with the disease) child🙈 please help!!!!
Zara Adam because cystic fibrosis is a recessive gene, I’m pretty sure ‘ff’ is a cystic fibrosis suffer
Zara Davies i thought so!! thank you
5:29 - what equipment brings it to 60°C? a water bath?
@@thecn83 yeah well done for your very helpful comment
Also yes I used a water bath in my in-school practical.
For practicals can u plz tell us why we put those things because in exams they always ask us questions like why did u put iced ethanol in? Tnxs
To make the DNA clump together
too extract the dna
iced ethanol is used because DNA is insoluble in that which is why it appears as a white stringy precipitate. Salt is added to clump DNA together and Detergent is added to break down the cell membrane so DNA is relaeased.
Hey, just to say the non coding is not junkDNA it's the instruction book for the codingDNA
night before/morning of anyone?
Good luck @cupcakemuffin128, I really hope you get all the questions you want!
@@Primrose_Kitten thank you soo much u r so sweeet!!!
