Question

Identify this structure.

A. Uracil
B. Adenosine
C. Adenylic acid
D. Cholesterol

Answer 1

Hint: It can be found based on the amount of oxygen, nitrogen, carbon and hydrogen present in that compound. Through this we can examine this structure. Based on the structure it has four oxygen atoms with two bonds, two hydrogen, carbon and two nitrogen.

Complete answer:
Uracil is a chemical compound as well as a nucleotide. It is the demethylated form of thymine. It is found in the nucleobases in nucleic acid in RNA. It binds to adenine through two hydrogen bonds. It is the demethylated form of thymine. This is replaced by thymine in DNA.

The following are some of the uses of uracil. They are as follows:
-It helps to carry out the synthesis of more enzymes for function of the cell through which the bonding is with ribose and phosphates.
-It serves as a coenzyme and allosteric regulator for both in animals and plants.
-It is also involved in the biosynthesis of polysaccharides.
-It can also be determined for microbial contamination of tomatoes.
So, based on the structure it has four oxygen atoms with two bonds, two hydrogen, carbon and two nitrogen.

Hence, the correct answer is option (A).

Additional information:
-Uracil is involved in transportation of sugars containing aldehydes.
-It provides hypermutations during the synthesis of vertebrate bodies.
-It promotes endopterygota development.

Note: Uracil is a primary nitrogenous base of RNA. There are four nucleobases in nucleic acid namely Adenine, Guanine, Cytosine, Uracil. As uracil contains all the three C, N, O denoting that it is Uracil which is present in RNA only.
