The correct arrangement of these biomolecules in increasing order of their molecular weight is
Options
- AATP, ADP, AMP, DNA
- BADP, ATP, AMP, DNA
- CAMP, ADP, ATP, DNA
- DDNA, ATP, ADP AMP
Correct answer
C. AMP, ADP, ATP, DNA
Step-by-step solution
AMP is Adenosine monophosphate. When one phosphate gets added it becomes ADP i.e. Adenosine diphosphate. Similarly when two phosphates get added it is ATP i.e. Adenosine triphosphate. Hence as phosphates get added, the weight increases. Therefore molecular weight of AMP ˂ ADP ˂ ATP. AMP consists of Phosphate + Sugar + Nitrogen bases = Nucleotides and DNA consists of millions nucleotides , hence molecular weight DNA is highest
