Because nitrogen cannot be transformed into ammonium sulphate at the conditions employed in the Kjeldahl technique, it cannot be used to estimate nitrogen levels in DNA and RNA. This test for DNA and RNA is limited due to the difficulties in dissolving ring formations.
In DNA and RNA, the nitrogen atom is present in the ring system. Can the Kjeldahl method be used for the estimation of nitrogen present in these? Give reasons.
