Question

Among the following compounds which are found in RNA?
A.

B.

C.

D.

Answer 1

Hint:RNA consists of Adenine, Guanine, Cytosine and Uracil. Thymine is not present in RNA instead it is present in DNA.

Complete step by step answer: Before directly getting to the answer we need to understand what is this RNA?
RNA or ribonucleic acid is a polymeric strand essential to carry on various necessary biological tasks which include coding, decoding, regulation, and expression of genes. These tasks are of utter importance as these tasks ensure that there is a proper transmission of genetic information from parent to offspring. mRNA or messenger RNA is the nucleotide chain that is responsible for the synthesis of certain proteins that is useful for the expression of genetic information carried from the parent.
So let’s analyse the given options
The first given structure is of thymine. Thymine is a well-known compound present in DNA or deoxyribonucleic acid. We till now know that RNA is made up of nucleotides that have pentose sugar into it ,which are composed of beta-d- ribose, phosphoric acid, and bases.
Now moving onto the third option we find out that this structure is of uracil. Now we know that both DNA and RNA contain four bases out of which three are common in them namely Adenine, Guanine, cytosine. But the fourth base is different from both of them. Hence the fourth base for RNA is uracil different from DNA’s thymine.
Hence to conclude this discussion we can say that uracil or option c) is the compound used in RNA.


Note: Both the RNA and DNA are the most important molecules in cell biology, how? Well DNA and the RNA can be called as the brain of a cell. All our genetic information from how we look to how we sound all this is stored inside this molecule. This defines the difference in different creatures and tells us how evolution occurs.
