About DNA/RNA Calculations

DNA and RNA are nucleic acids essential for life. Their molecular weight and concentration are important for molecular biology, genetics, and biotechnology.

Key Formulas:

  • Molecular Weight (DNA): dsDNA ≈ (number of bp × 650 Da), ssDNA ≈ (number of nt × 330 Da)
  • Molecular Weight (RNA): ssRNA ≈ (number of nt × 340 Da)
  • moles = mass / MW
  • mass = moles × MW
  • concentration = mass / volume

Units:

  • Mass: μg, mg, g
  • Moles: mol, μmol, nmol
  • Concentration: ng/μL, μg/mL, nM, μM

Applications:

  • PCR, qPCR, and sequencing
  • Cloning and gene expression
  • Biotechnology and diagnostics
