AQA Biology AS New Spec - 26th May and 7th June

Just realised I compared prokaryotic DNA and eukaryotic DNA instead of DNA and RNA.....

Whoops!
What did you write?

-Anis

I said about DNA being associated with histones

DNA is linear not circular

DNA is in the form of chromosomes

I had just done a past paper which asked to compare prokaryotic and eukaryotic so I think I just had that in my head and barely read the question...its such a daft way to loose 3 marks!

Unfortuately, you wouldn't get any marks for it.
What you could've written was;
- DNA is double Stranded
- DNA has Deoxyribose
- DNA has Thymine, instead of Uracil
(accept converse)

What did people put for what type of transport is used ?? It said like co transport and facilitated diffusion

I put that MRNA Doesn't have hydrogen bonds whereas DNA does, I'm sure that would get the marks too

Wellllll obvs I know that lol I just misread the question

I put Chi-squared, but apparently, it was T-Test.

Also what was the answer to question which talked about why 100 mol dm-3 should be used? I think a student said it was the best way

My teacher gave me a list of maths skill we a required to know for as and a2 and t-test, chi square, c.coeff are not for AS, we even asked our teacher (my class) and she said we deffo don't need to know this stuff for the paper this year....

We hadn't even been told anything about statistical tests! I didn't even know they came into biology, and wouldn't even know what a statistical test was if it wasn't for the fact I've done the sign test in psychology.
