aqa gcse biology paper 2 100
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?
◍ what is pre mrna. Answer: pre mrna only produced in eukaryote
cell. splicing only occurs in eukaryote cell.
