DNA Copy Number
Calculate the number of DNA molecules from mass in nanograms and length in base pairs.
Description
Calculate the number of DNA molecules from mass in nanograms and length in base pairs.
DNA Copy Number is a focused biology tool that calculate the number of DNA molecules from mass in nanograms and length in base pairs. It calculates locally from the values you enter and exposes the result without changing the source observations.1
When to use DNA Copy Number
Use DNA Copy Number when you need to calculate the number of DNA molecules from mass in nanograms and length in base pairs. Enter Mass and Length using the definitions and units below so the result can be reproduced.
- Mass
- A finite measured or assumed value, expressed in ng.
- Length
- An integer count or setting, expressed in bp.
How DNA Copy Number calculates the result
The published tool contract uses this rule: Calculate the number of DNA molecules from mass in nanograms and length in base pairs.
- Copy count
- The calculated copy count.
Limitations of DNA Copy Number
The calculation does not propagate measurement uncertainty, sampling error, or biological and chemical variability.
Alternative or Complementary measurements
Retain the original Mass and Length values and their units alongside the result. RNA Copy Number is useful when you instead need to calculate the number of RNA molecules from mass in nanograms and length in nucleotides. qPCR Copy Number provides another view by helping you convert a double-stranded DNA mass in nanograms to molecule count using length and the mean base pair mass of 650 daltons.
