❤ GOODLUCK tomorrow everyone!

what a legend

2023 🎉

Hello, I’m confused on the difference between genes and DNA? I thought it was DNA sequence that determines the amino acids, but here you have said its the base sequence of the gene. Are they interchangeable? Or is gene just one of the triplets of bases (e.g ATG) and the DNA is the entire sequence with multiple triplets of bases

THANK YOU!!!!

ngl this is hard

Thanks so much for this! I understand it now

Hi Sir, thanks for the video! but i just wanted to ask if the gene is switched off when its meant to be on what effects could this have?
thank you.

Hi on my textbook it tells me there are different types of mutations (e.g. deletions or insertions) - do we need to know this for the AQA specification?

Ya'll better be watching the ads on these videos

The lord is back

Anyone here after the school closure announcement March 2020 frantically revising for last minute mocks???

exam tomorrow :)) good luck everyone!

Mutation is the formation of the first DNA strand abnormal?

Thank you so much! I just have one question, if a mutation occurs, does that alter the complementary base pairing? And so does that cause another mutation?

do we need to know about gene expression because its in my aqa textbook? if so can you briefly describe it because i don't really understand it. thanks a lot

What’s the difference between a phenotype and genotype

My college entrance exam is 1 week before now, these is really helpful I hope I can make it

exam is tomorrow:/

Exam is tommorow GL Guys!

I find your videos very helpful, do you think you could do the a level course as I'm​ doing it next year?

Sir isn't this topic also included in the combined science specification?

Congrats on 100k!!
