    i didn't do French, but I'd say that meant 'common sense is very/extremely rare'? Got that by thinking, using my common sense, rather than having learned anything about it ;)
    (fort being akin to strong, so if u said 'strongly rare' I'd assume you meant 'very rare').

    I like the way you think ;)

    I prefer le sens commun n'est pas si commun. I actually used that in my French essay now that I remember it. :p

    I prefer using the correct version :p (I used it in my mocks, and a different Voltaire one in my LC French essay!)

    The outrage over the ecology question is ridiculous though. I did fairly poor in it now that I think about it, due to not doing well with the quantatative survey questions, but its 1 question out of 6. I did all of them and those with "booksmarts" should have been able to as well. The ecology question really shouldn't have made all that much of a difference in the end if they had learned all the other stuff.

    The ecology question wasn't out of line with previous years, only the part B required to think outside the box a bit, if you'd call that thinking outside the box (I'd call it common sense...)

    There were another 5 questions in section C. Genetics was the easiest it's ever been imo, the nephron came up as expected, and the tension-cohesion model was also due.

    I think it was a fair exam, but for the A1 you had to have a good knowledge of nearly all the course since they threw in bits and bobs everywhere. I also think they're making more of a move towards the "make you think" questions in recent years, as evidenced with this years ecology questions and the glucose/protein in urine question this year.

    It has also been evident in how they're approaching the experiment questions, throwing in small parts of a few experiments into each question (2010+2011) and also in some of the long questions the Q15(c) has been a range of unrelated statements from a few parts of the course (2009+2010). I think in general there are a lot of exams starting to cut out the predictability and the chancing.

    Oh yeah, that's right, the scientific method question this year (Q6 I think) was very much off-the-cuff. How to sterilise compost like, had to use the ceann!

    A PROTEIN IS A VERY LONG POLYPEPTIDE WITH AT LEAST 200 AMINO ACIDS.

    there are 200 amino acids in a protein.

    Err... thank you for letting us all know?

    But the questions was, how many ammino acids are there in general.
    It was just worded badly.
    So the answer is 20.

    Nope it was looking for the common 20. And you said it yourself at least 200 amino acids, not just 200!

    The question was, how many common amino acids are there in a protein?

    Is it fair to say that it depends on the protein?

    That is technically right.


  • Registered Users, Registered Users 2 Posts: 163 ✭✭Geog ariphic


    It does say in my book that nine amino acids are common, but that there are 20. I know that some ppl said 9 in my school. Think they'll get allowances?

    Why what you say?


  • Closed Accounts Posts: 494 ✭✭PJelly


    Why what you say?
    I said 21.
    I was nearly sure it was 21... But loads of my friends came out saying 20.


  • Registered Users, Registered Users 2 Posts: 163 ✭✭Geog ariphic


    Another case of the course vs reality, methinks.
    Seriously, it got so bad for the human body, Heart especially, that they were accepting on marking schemes "any correct medical reference"

    That made absoloutly no sense


  • Registered Users, Registered Users 2 Posts: 163 ✭✭Geog ariphic

    EDIT: This is another case of the information on the leaving cert biology course vs. the reality of biological facts, I believe. (Methinks being a Middle English word, popularised today by Shakespearean, meaning 'It seems to me.' or similar.)
    [tell me if i'm going too fast]
    For questions pertaining to the human body, in particular to the organ of the heart, that it has been seen on marking schemes that they will now accept "any correct medical reference", as they acknowledge that people have actual medical information on this and other organs that may conflict with or be surplus to the requirements of the leaving cert biology course.



    I don't like spelling out things that i have already said, so you'll have to excuse the slightly condescending tone of the above piece. It's nothing against you.

    Take it easy, I had to read your original post twice myself to figure it out! :)


  • Registered Users, Registered Users 2 Posts: 163 ✭✭Geog ariphic


    Oh bugger.
    I posted an apology but its not here...keep getting signed out.
    I did just loose the head a bit Little Miss Lost, it was my problem, not yours.
    Wan't trying to offend you at all. Sorry.


  • Closed Accounts Posts: 5,109 ✭✭✭QueenOfLeon


    The question was too vague. I do think that the answer was 20, but it wasn't really worded correctly. But in the grand scheme of things...it was in Question 1, where you get marked for 5 answers out of 6 questions. If you had gotten all the other parts right (which were relatively basic) then the protein one isn't going to count for you at all. Chill, relax, forget about it, go enjoy your summer or get ready for the rest of your exams! :P


  • Closed Accounts Posts: 5,734 ✭✭✭J_E


    Chances are they won't mark it for a lot if the majority of people got it wrong.


  • Registered Users Posts: 99 ✭✭sarah.


    Ok people need to stop worrying now and just enjoy the summer/get ready for the last few exams! I worried a lot about little things like the protein question as well but now its time to end the post mortem on Biology! Concentrate on doing well in other subjects you may have left or on having the best summer yet! :D

    Yeah ,They will know how to mark it themselves , we dont know the markin scheme so no point in stressing

    "How many common amino acids are found in proteins?"

    The answer that the marking scheme will most likely be looking for is 20, as this is the standard amount in the genetic code of most organisms, including humans. However 21 and 22 should be acceptable answers too, as certain organisms contain an extra amino acid sequence specified in their genetic code which is translated also, such as Selenocysteine in some bacteria and Pyrrolysine in certain archaea.

    i think it says 20 in our biology book not 21

    Are archaea eukaryotes? Just from the name i'd imagine they aren't but i've no idea - 21 for eukaryotes is what wikipedia says...:rolleyes:


  • Closed Accounts Posts: 28 Ivan Offlcockitch


    Will ye STOP going on about the amino acid Q!!!
    It was a SHORT question.
    It was part of a MULTIPLE CHOICE question where if you have the other 5 right you will be fine.
    It is worth 4 MARKS.

    Can everyone just accept the answer being looked for is 20 but 21 or 22 will most likely get the marks.
    Now can everyone just GET OVER IT and move on!!!


    ........Enjoy the summer everyone.smile.gif

    Now that we're apparently over that hump, here's something else which could be controversial:

    "9. (a) (i) How are the two strands of a DNA molecule joined together?"

    I said DNA Polymerase. I'm pretty sure what they were looking for was to name the bond, but technically that is how they become joined together, yes?

    I said a double helix shape with complimentary pairs joining each other. I don't know really.


  • Closed Accounts Posts: 28 Ivan Offlcockitch


    hydrogen bond was what i said i think


  • Registered Users, Registered Users 2 Posts: 479 ✭✭LittleMissLost


    hydrogen bond was what i said i think

    I said weak hydrogen bonds..
    That's also what it says in my notes. If they don't give me the marks because I put "weak" in I'll flip :eek::mad:


  • Closed Accounts Posts: 7 leaving cert finished 2k11


    for the amino acid question the answers 20 21 22 will be acceptable and maybe ppl will be rewarded for stating the number of amino acids that are necessary to form a protein...what was any of yer answers to question 4 on the graph of human body temperature when it asked wat is the maximum temperature range under normal conditions..i said 1.6 as i took lowest temperatue from highest temperature??


  • Registered Users Posts: 202 ✭✭GSI


    I can't believe this thread is still alive. Jesus christ, I'd forgotten about biology an hour after the exam:/


  • Closed Accounts Posts: 7 leaving cert finished 2k11


    ya i said hydrogen bonding between base pairs but id say dan ligase and dna polymerase will also be acceptable :D
