AQA as biology paper 2 Questions with Answers
what term is used to describe the different structures of a glucose and b glucose? [1mark] - correct
answers>>>hydroxyl group
describe how the result from the colorimeter can identify the fruit juice containing the higher sugar
content [1 mark] - correct answers>>>juice b
suggest how pna affected the transcription of the section of dna [2 marks] - correct answers>>>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 in a prokaryotic cell[2marks] - correct answers>>>eukaryotic transpiration takes
place of the nucleus,while prokaryotic transcription takes place in the cytoplasm.
describe the role of atp in the process of translation in protein synthesis[2marks] - correct
answers>>>the formation of a peptide bond between amino acids requires energy in the form of atp.the
atp needed for translation is provided by the mitochondria within the cell
describe the structure and function of the nucleus[4marks] - correct answers>>>a membrane bound
structure that contains the cell's hereditary information and controls the cell's growth and reproduction.
it is separated from the cytoplasm by a nuclear membrane.
command center of a eukaryotic cell.
the shape is disc shaped
the student controlled variablea in the test using benedicts solution. give two variables the student
controlled.[2marks] - correct answers>>>1 sample volume
2 temperature
What is a gene? - correct answers>>>segment of DNA that codes for a protein. a sequence of dna
nucleotide bases that codes for a polypeptide.
ZO-1 question? - correct answers>>>zo1 is located in cell surface membrane.
2 antibody is complementary to zo1 .
