    How do you propose different lengths of proteins are made aside from due to splicing and post transcriptional changes, if the same gene is used? I'm pretty sure they said the proteins were coded for by the same gene. Can't be entirely sure tho.
    Yeah it was about how different sized PROTEINS where coded for by the same GENE, so splicing, exons and introns and all of that I guess

    This paper was a lot similar to Jan 14 IAL (just worded slightly differently with difference applications) and that was 62 for an A* and 57 for an A grade. It will probably be 60 or 59/58 for an A but in honesty I thought this paper was easier than the June 15 paper!

    didnt mention structure at all though
    Pretty sure it just asked for differences between them and not specifically structure, remember reading it twice prior to answering the question

    Does anyone remember the order the questions came up in and the mark allocations

    My school is complaining about the clarity of the plasma image, hopefully they'll do something about it
    oh come on....it was obvious as hell what they wanted. Don't get me wrong it was a hard paper but a golgi apparatus is not that big and not that straight.

    True but then some people thought it was a smooth ER as the ribosomes on the surface of the ER to suggest it was a rough ER

    For the MCQ of structure r, was it a nucleus, lysozome, vacuole of cytoplasm? The one that was pointing furthest inside the structure

    I got 13.75% as I thought it said available from 2nd trophic level to the 4th so surely you'd do GPP-R for the second trophic level and the same for the third trophic level then work the percentage from those values

    Yeah it was impossible to tell between SER and RER using only the image. I wrote ER on it's own :/

    I reckon you could argue the case of a golgi also due to the lack of distinction between the structures. As antibodies are 3D proteins with a specific shape, the modification of primary structure to the specific structure could be what they meant by 'production of antibodies'

    Why edexcel why? What is the point? We were tested on this last year. How was this a productive exam? Testing us if we can churn out the same stuff from last year. Great. Thanks. What a waste of time learning photosynthesis was and most theory in UNIT 4. JOKE.

    That's exactly what I'm thinking.

    guys thinking about it, there were only AS qs, data qs, and a few a2 qs. No viruses, no tb, no photosynthesis, no immunity qs ( besides the b cell 3marker)
