How to use the gene length from protein calculator
Find coding sequence length from protein size. Enter amino acids in the field above; the coding dna, codons are computed instantly and plotted on the chart so you can see how the answer changes.
Formula
Variables
- aa — Amino acids
Worked example
With amino acids = 250, the calculator gives coding dna ≈ 753 bases; codons ≈ 251.
Frequently asked questions
What is the formula for the gene length from protein calculation?
Coding DNA (bases) = 3 × (aa+1). Codons = aa+1. Here aa is amino acids.
What inputs do I need for the gene length from protein calculator?
You need amino acids. Each field is pre-filled with a typical example so you can see how the result responds as you edit the numbers.
How do I use this calculator?
Type values into the input fields. Results and the chart update instantly. Use Reset to restore the example values, Copy results to paste them elsewhere, or Share to copy a link that preserves your inputs.
Is the result exact?
Calculations use standard formulas and double-precision arithmetic, then display about seven significant figures. Real-world measurements carry uncertainty, so treat results as estimates unless your inputs are exact.
