The Base Pair to kDa Calculator helps researchers and students calculate the molecular weight of DNA or RNA sequences in kilodaltons (kDa). This tool is ideal for understanding the size of genetic sequences, aiding in molecular biology experiments and research.
Formula
The formula to calculate molecular weight is:
MW = BP * CF
Where:
- MW = Molecular weight in kilodaltons
- BP = Number of base pairs
- CF = Conversion factor (weight of each base pair in kDa)
How to Use
- Enter the number of base pairs (BP) in the input field.
- Provide the conversion factor (CF) for base pairs in kilodaltons.
- Click the Calculate button.
- The molecular weight (MW) in kDa will be displayed in the result field.
Example
For a DNA molecule with 3000 base pairs and a conversion factor of 0.65 kDa per base pair:
MW = 3000 * 0.65 = 1950 kDa
The molecular weight is 1950 kDa.
