How can I use SnapGene to calculate the molecular weight, mass, concentration and copy number of a DNA or RNA sequence?
Open a DNA Sequence
Open a DNA sequence of interest.
If you wish to calculate information for a portion of the sequence then select the region. In the above screenshot a BamHI-SphI restriction fragment has been selected.
Click DNA Calculations
Click Tools → Show DNA Calculations.
1. Calculations for the full length sequence are always shown at the top of the window.
2. Calculations for a selected region are shown (if a region is selected) towards the bottom of the window.
