Prep Material
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] -

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.

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
