❓ Frequently Asked Questions

🔹 What is DNA concentration?

DNA concentration refers to the amount of DNA present per unit volume, commonly expressed as ng/µL.

🔹 How is DNA concentration calculated?

It is typically calculated using UV absorbance at 260 nm, dilution factor, and standard conversion coefficients.

🔹 Why is DNA concentration important?

Incorrect DNA concentration can lead to PCR failure, sequencing errors, and inaccurate experimental outcomes ❌.
