The correct arrangement of these biomolecules in increasing order of their molecules weight is

Options

A. ATP, ADP , AMP, DNA
B. ADP, ATP, AMP,DNA
C. AMP, ADP,ATP, DNA
D. DNA, ,ATP , ADP, AMP

Answer

To determine the correct arrangement of the biomolecules ATP, ADP, AMP, and DNA in increasing order of their molecular weight, we can follow these steps:

### Step 1: Identify the Molecular Weights
- **AMP (Adenosine Monophosphate)**: The molecular weight of AMP is approximately 347 g/mol.
- **ADP (Adenosine Diphosphate)**: The molecular weight of ADP is approximately 427 g/mol.
- **ATP (Adenosine Triphosphate)**: The molecular weight of ATP is approximately 507 g/mol.
- **DNA (Deoxyribonucleic Acid)**: The molecular weight of DNA varies greatly depending on the length of the DNA molecule, but a single nucleotide unit can be around 330 g/mol. However, a typical DNA molecule is significantly larger, often in the millions of g/mol range.

### Step 2: Arrange in Increasing Order
Now that we have the approximate molecular weights, we can arrange them in increasing order:
1. **AMP** (347 g/mol)
2. **ADP** (427 g/mol)
3. **ATP** (507 g/mol)
4. **DNA** (much larger than the others)

### Final Arrangement
Thus, the correct arrangement of these biomolecules in increasing order of their molecular weight is:
**AMP < ADP < ATP < DNA**

### Conclusion
The correct option is the one that lists AMP first, followed by ADP, then ATP, and finally DNA.
