[1mark] hydroxyl group describe how the result from the colorimeter can identify the fruit juice containing the higher sugar content [1 mark] juice b suggest how pna affected the transcription of the section of dna [2 marks] tight binding to mrna due to the strand displacement in a dna target describe how the production of messenger rna (mrna) in a eukaryote cell is different from the production of mrna...

large molecules often contain carbon. why? they can readily form bonds with other carbon atoms. this forms a 'backbone'. other atoms can then attach. describe benedicts test for reducing sugars add equal volumes of the sugar sample and benedicts reagent. heat the mixture in a water bath for 5 minutes. brick red precipitate will form. what is a reducing sugar? a sugar that can reduce (give electrons to) another chemical. describe the benedicts test for non reducing sugars with food sampl...
