DNA Copy Number Calculator
Calculate the absolute number of DNA copies from mass and template length in base pairs using Avogadro's number.
Input Parameters
Instant Real-time CalculationCalculated using: Copies = (Mass in g * Avogadro) / Molecular Weight. For dsDNA, average weight per base pair is ~660 g/(mol*bp).
