The positive result- the resulting blue solution, indicates that the test carbohydrates is a pentose(ribose for example). The blue color is due to the iron content of ferric chloride.

What does bials orcinol determine in nucleic acid?

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 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.


How would you be able to determine from where nutrient influx comes?

You can test the nutrient influx by using a water test. You will determine the historical patterns and then collect water samples from the surface and subsurface layers along the estuaries.

What test is specific for pentose?

The specific test for pentoses is the Bial's test. This test involves heating the sugar with orcinol and an acidic solution, resulting in a blue-green color if pentoses are present.


Will a DNA test tell if I cheated?

No, a DNA test is used to determine genetic relationships between individuals, such as paternity or ancestry, by comparing DNA samples. It will not conclusively indicate if you have cheated on someone.


What is procedure of core test?

The core test procedure involves drilling a borehole into the earth's subsurface to extract cylindrical rock samples, known as core samples. These samples are then analyzed in a laboratory to determine properties such as composition, porosity, permeability, and other physical characteristics. The results of the core test help geologists and engineers understand the geological properties of the site for various purposes, such as mineral exploration, environmental assessments, or geotechnical investigations.


What is the process for conducting a prenatal paternity test for twins?

The process for conducting a prenatal paternity test for twins involves collecting DNA samples from the twins and the potential father through a non-invasive procedure, such as a blood test or cheek swab. The samples are then analyzed in a laboratory to determine the genetic relationship between the twins and the potential father. This test can be done as early as 9 weeks into the pregnancy.
