AQA Human Biology unit 4 (HBIO4) - 15th June 2012

I said it had a high chance, since the restriction enzyme didn't work!

what did everyne write about the advantages about agnostic muscles? Didn't really understand :/

The baby shouldn't have sickle cell anemia... nor does it have the trait. Only 110 length DNA was present which means that the enzyme did not work on any strands of the DNA of the fetus. The baby inherited the H^a alleles from both the mother and father.
That is what I think

1. When one muscle contracts, the other is relaxing - does not overwork muscles.
2. Arms can move both ways: both forwards and backwards.

I think!

I didn't like the fetus question and I didn't like the footballer question. Everything else went ok hard to tell how you've done with Human Biology though! :/

Exactly only 110 DNA was present, it didn't cut the DNA at all! The whole point of the restriction enzyme was to cut the NORMAL DNA - if the normal DNA is not present then no cutting will occur. The DNA did not get cut hence the baby will have .

PS the parents will have to have the gene as sickle cell is co-dominent. They produce both forms of DNA hence will have BOTH alleles present

That's exactly what I wrote, hope it's right! hmmm.....

Actually the Dder enzyme was to cut the DNA that coded for sickle-cell anemia. Yes the parents are heterozygous and so there is a chance that they can have a baby without the sickle-cell trait.

I'm really curious about this sickle-cell question now! lol anyone got the paper?

How did you guys find the hormones questions?

mind has completely gone blank, what were the hormone questions? I can remember the definition question and the 5 mark one during pregnancy that was a nice question.

Don't think I got the definition right, but yeah the 5 marker description was pretty nice

Can't really remember the rest There was the last question, the asked about the person news reporter thinking alcohol and caffeine affect FSH concentration.

did you have to talk about the:

-Sample size
-Age range (FSH concentration in older women may be higher)
-the P>0.05

Yeah I said all that and that some of the women may have started their menopause so the concentrations of FSH may have been affected by this. I can remember writing about 10 points for this question but completely forgot what else I wrote lol.

the Bt gene questions were OK, still pretty hard to realise what the actual mark points were

On the whole it seemed like a bad'ish paper tbh
