    I think you didn't understand what I'm trying to say. The thing is DCPIP becomes colourless but in the presence of chlorophyll shouldn't it remain green? As a result, the absorption will be at a higher level than zero. Also, the plateau reaches constant value of 0.6 au (I think) at 7.9 (or earlier) right?

    it wasn't bad man...honestly i havent spent too much time studying bio and i expected to write utter shit in the exam (excuse my words) but it turned out really well (ofc some mistakes here and there) but hopefully the Marking Scheme is in our favor (same with the threshold and paper 1)

    Transcription and translation - Interphase
    Spindles start to form - Prophase

    Not necessary for glycosidic bonds, it was for only 2 marks
    I wrote about it being formed by condensation reaction by the liniking of monosachrides with the removal of water molecule
