AQA AS Biology - BYA2

Just finished this about an hour ago, what did everyone think of it?
For the question on PCR I wrote a detailed description of genetic fingerprinting, then i realised, and had to re-answer the question on the back of the paper *slaps forehead*.

Its just getting all the points they ask for in the mark scheme, AQA is very stirct in that way.

argh, my back is killing me from sitting for 3 HOURS doin all 3 bio modules! lol

erm i found most of the q's to be fine, got a lil confuddled wit the con desity of the blue solution ....and the maths lol-but im pants at that tho thought i did ok!
-u mean the plant where the phloem had been cut out so the sugar solution was higher at the topt han bottom rite?
basically-sugar will move up n down te plant in the ploem, but by removing it, all the sugar that is already at the top of the plant will not be able to come back down, by travelling up the xylem, more sugar will go to the top of the plant, therefore builds up as none can go back down, therfore the conc is higher than in the control, where the sugar can travel up n dowwn :smile:

lol

but yeah thought it was all ok really

I did BYA2 as well and there was no question about a blue solution.

Maybe yours was specification B

I did AQA-B 2 and 3

For once I thought 3 was harder than 2 but I revised like crazy and think I did pretty darn well!! I even remembered the interphase, prophase etc etc :smile:

What were the two pictured stages of mitosis near the start of the paper?

Also, was the "How many bases" question: 3 x 1480 = 4440?

What were TWO concerns some people might have with genetically modified maize?

I also did spec A (sorry for not making that clear!).

There was actually an error on the hormone cycle graph. They had swapped around 2 hormones. My teacher himself told me that there was an error. Was anyone informed of this before starting the exam? If not, will we be automatically awarded marks for that question or what?

is this hormone question on the spec A BYA2?

I don't remember noticing it, but then I didn't really look at the graph, there all the same and so I just answer question as normal.
Although the graph was a bit confusing as all the lines looked very similar, especially when they crossed, we need colour versions :smile:

That question has come up so many times before, I doubt if many people will have noticed.

if it was an error what do they normally do? Its strange they didn't pick up on something like that before exam.

They'll probbaly try and keep it all hush hush and hope no one complains

I got 4440 for an answer and i'm positive that's right.
For the pics I guessed prophase (i don't know if it could have been interphase) and anaphase.
