what term is used to describe the different structures of a glucose and b glucose? [1mark] -
(answer)hydroxyl group
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.
