Question 17

5 mark question comparing DNA in eukaryotic cells vs prokaryotic cells

Answer 17

DNA is associated with histones in eukaryotic- not in prokaryotic
DNA is linear in eukaryotic, circular in prokaryotic
Eukaryotic DNA is longer than prokaryotic DNA
Eukaryotic DNA contains introns, prokaryotic DNA does not
SAME nucleotide base sequence- deoxyribose sugar, nitrogenous base and phosphate groups
Phosphodiester bonds joining DNA together
