Expert Solution
Step 1

DNA and RNA are the nucleic acids that are made up of nucleotides. The concentration of these biomolecules in biological samples can be determined by one of the most important techniques called nano drop technique, which is a spectrophotometric analysis. The technique can measure the concentration and purity of nucleic acids at a very low concentration level ( Ex:  less than 10 ng/ microlitre)
