AQA BIOLOGY PAPER 2 TEST BANK
EXAMINATION TEST TEST PAPER
QUESTIONS AND SOLUTIONS 2026 GRADED
A+.
⩥ describe how the result from the colorimeter can identify the fruit
juice containing the higher sugar content [1 mark] Answer: juice b
⩥ suggest how pna affected the transcription of the section of dna [2
marks] Answer: 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] Answer: 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] Answer: 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] Answer:
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] Answer: 1 sample
volume
2 temperature
⩥ What is a gene? Answer: segment of DNA that codes for a protein.
a sequence of dna nucleotide bases that codes for a polypeptide.
⩥ ZO-1 question? Answer: zo1 is located in cell surface membrane.
2 antibody is complementary to zo1 .
3 so binds to the zo1.
4 cells identified with dye linked to antibody
⩥ DNA replication during interphase. two divisions. separation of
homologous chromosomes. separation of sister chromatids. produces
4 haploid cells. Answer: How many daughter cells are produced at the
end of meiosis?
