Bial's test is used to determine the presence of a pentose sugar. For example, the sugar ribose would turn green (positive) and the sugar glucose would turn brown or yellow (negative).
Nucleic acids (DNA and RNA) both contain a suger. RNA contains ribose, so it should have a positive orcinol test. DNA contains deoxyribose, which should have a weak reaction, yielding what appears to be a negative result.
What else can I help you with?
What is the reaction mechanism of orcinol in the estimation of RNA?
Furfural cannot be formed from ribosides until the glycosidic linkage has been split; the purine-ribose links of RNA are easily hydrolysed by hot acid, while the pyrimidine-ribose links are much more resistant, and the orcinol method is commonly supposed to determine only the purine-bound ribose of RNA.
What is the full name for DNA and RNA?
DNA- Deoxyribo Nucleic Acid RNA-Ribo Nucleic Acid
What type of biological molecule is DNA?
DNA is a nucleic acid, which is a type of biological molecule that carries genetic information in living organisms. It consists of a double helix structure made up of nucleotides containing a sugar, a phosphate group, and a nitrogenous base.
What is a common name of nucleic acid?
Nucleic acid is one of the 3 parts of nucleotides and can also be called DNA.
What is a nucleic acid coated with a protein?
A viral nucleic acid coated with a protein is called a capsid. The capsid helps protect the nucleic acid and aids in the virus's ability to infect a host cell.
Is DNA a amino acid or is it a nucleic acid?
A nucleic acid.
What is the reaction mechanism of orcinol in the estimation of RNA?
Furfural cannot be formed from ribosides until the glycosidic linkage has been split; the purine-ribose links of RNA are easily hydrolysed by hot acid, while the pyrimidine-ribose links are much more resistant, and the orcinol method is commonly supposed to determine only the purine-bound ribose of RNA.
What is the full name for DNA and RNA?
DNA- Deoxyribo Nucleic Acid RNA-Ribo Nucleic Acid
What does bial-orcinol reagent composed of?
300 mg of orcinol in 100 ml of conc. HCl and 0.25 ml of ferric chloride solution (10g / 100ml ).
Is phosphoric acid a carbohydrate lipid protein nucleic acid?
It is a nucleic acid.
What kind of acid is in a molecule that carries a genetic information?
Nucleic acids:Deoxyribose Nucleic AcidRibose Nucleic Acid
What is Principle behind using orcinol reagent in extraction of RNA from yeast?
The method depends on conversion of the pentose, ribose in the presence of hot acid to furfural which then reacts with orcinol to yield a green color. The color formed largely depends on the concentration of HCl, ferric chloride, orcinol, the time of heating at 100°C etc up to certain maxima.
What nucleic acids are involved in transcription?
Deoxyribose nucleic acid, transcribed into, Ribose nucleic acid.
What makes a nucleic acid a nucleic acid?
DNA and RNA
Does DNA help Synthesize Nucleic Acid?
DNA is a nucleic acid.
What is the polymer for nucleic acid?
A nucleic acid is a polymer made of nucleotides.
Two varieties of nucleic acids?
DNA (Deoxyribo Nucleic Acid) and RNA (Ribo Nucleic acid).
