The Base Pair to Dalton Calculator is a simple yet powerful tool that calculates the molecular weight of DNA or RNA sequences in Daltons. It uses the number of base pairs and a conversion factor for precise results, assisting researchers and students in the field of molecular biology.
Formula
The molecular weight is calculated using the formula:
D = BP * CF
Where:
- D = Total molecular weight in Daltons
- BP = Number of base pairs
- CF = Conversion factor (weight of each base pair in Daltons)
How to Use
- Input the number of base pairs (BP) in the first field.
- Enter the conversion factor (CF) for the weight of each base pair in Daltons.
- Click the Calculate button.
- The total molecular weight (D) in Daltons will appear in the output field.
Example
If a DNA molecule has 2,500 base pairs and each base pair weighs approximately 650 Daltons:
D = 2500 * 650 = 1,625,000 Daltons
The molecular weight of the DNA sequence is 1,625,000 Daltons.
