Why does the Diphenylamine test only react with DNA?
The Diphenylamine test is specific to DNA because it reacts with the deoxyribose sugar present in the DNA backbone. The test detects the presence of DNA by forming a blue color complex with the deoxyribose, which is unique to DNA and not found in other nucleic acids like RNA.
DNA estimation by DPA method?
in DNA estimation by diphenylamine method, standard calf thymus DNA is digested by perchloric acid, but unkown is not digested by perchloric acid, rather rest protocol of diluting with water and treating with diphenylamine and checking aborbance reamins same can anybody say the reason?
What sugar is present in deoxyribose RNA?
The sugar present in deoxyribose RNA is deoxyribose.
Which sugar present in DNA?
Deoxyribose sugar, it is a pentose sugar base.
What is the role of deoxyribose in the synthesis of RNA?
Deoxyribose is not directly involved in the synthesis of RNA. RNA is made up of ribose sugar, not deoxyribose. Deoxyribose is found in DNA, not RNA.

What color changes indicate a positive result for dische diphenylamine?
A positive result for dische diphenylamine test would be indicated by a deep blue color change in the solution. This color change indicates the presence of DNA, as dische diphenylamine reacts with deoxyribose sugars in DNA to produce a blue color.
Why does blue colour appears in diphenylamine test?
The appearance of a blue color in the diphenylamine test indicates the presence of a reducing sugar, such as a reducing sugar or pentose sugar. The reaction occurs when the sugar present in the sample reduces diphenylamine to form a blue compound.
Does water react with diphenylamine?
One major difference between DNA and RNA is their sugar: DNA contains deoxyribose, whereas RNA contains ribose. This is what isdiphenylamine testfor deoxyribose for. In this process, the reaction between the Dische reagent and 2-deoxypentose results in the development of a blue color. The reaction depends on the conversion of the pentose to w-hydroxylaevulinic aldehyde which then reacts with diphenylamine to give a a blue colored complex. The intensity of the blue color is proportional to the concentration of DNA. Dische reagent does not react with the ribose sugar in RNA and does not form a blue-colored complex.Dische diphenylamine test-- A chemical test utilized to detect the presence of DNA in a substance.Mudit Mishra
WHAT IS TEST REAGENT USED TO IDENTIFY NITRATE ION?
A common test for nitrate ion is with diphenylamine.
How to prepare nitrate test solution using diphenylamine in sulphuric acid?
To prepare a nitrate test solution using diphenylamine in sulfuric acid, you can mix diphenylamine with concentrated sulfuric acid in a specific ratio. Typically, a 0.1% diphenylamine solution in concentrated sulfuric acid is used for nitrate testing. Follow safety precautions when working with concentrated sulfuric acid as it is corrosive.
What will diphenylamine turn blue in the prescense of?
Diphenylamine turns blue in the presence of nitrates. This reaction is commonly used in the Griess test to detect the presence of nitrate ions.
DNA estimation by DPA method?
in DNA estimation by diphenylamine method, standard calf thymus DNA is digested by perchloric acid, but unkown is not digested by perchloric acid, rather rest protocol of diluting with water and treating with diphenylamine and checking aborbance reamins same can anybody say the reason?
When does a spray of diphenylamine reagent on TLC gives blue coloration?
Diphenylamine is a reagent for DNA.
Diphenylamine will turn blue in the presence of?
DNA
Is diphenylamine organic or inorganic?
Diphenylamine is an organic compound. It is a derivative of aniline and is commonly used as an antioxidant in various industries, including the production of rubber, plastics, and explosives.
What is the structure of diphenylamine?
Diphenylamine has a simple structure consisting of two benzene rings connected by an amino group (-NH-). Each benzene ring has a phenyl group attached to it.
