Question

Nitrogen bases of RNA are:
(a) ATCG
(b) ATUG
(c) AUTC
(d) AUCG

Answer 1

Hint: The full form of RNA is Ribonucleic acid. It is a macromolecule which is essential for all forms of life. RNA is made up of one sugar and four nitrogenous bases. The important role of RNA is to convert the information stored in DNA into proteins. It is present in panoply of human fluids

Complete step by step solution:
RNA are divided into three parts and they are m-RNA , r-RNA and t-RNA. M-RNA is known as messenger ribonucleic acid which plays an important role in our body. It plays an important role in protein synthesis. It is a single stranded molecule which generates the genetic code from deoxy ribonucleic acid in the cell nucleus to ribosomes. It moves to the cytoplasm where the protein is made. r-RNA is known as ribosomal ribonucleic acid. It associates with proteins to form ribosomes. They are complex structures which help in catalysis of amino acids into proteins. They also help to bind t-RNA and other necessary molecules to form proteins. t- RNA is known as transfer RNA which helps in protein synthesis.
It has two important areas which are the trinucleotide region which is called anticodon and the other region is that where a specific amino acid is attached. The RNA is made up of four nitrogenous bases and a sugar. The sugar is ribose. The four nitrogenous bases are adenine, guanine, uracil and cytosine.

So the correct option for this question is option ‘d’.

Note: Adenine is purine which helps in cellular respiration, in the form of adenosine triphosphate. Guanine is used in signaling inside the cell. It is a purine. Thymine is a pyrimidine which is used to stabilize the nucleic acid structure. Uracil is the base which helps us in synthesis of enzymes. It is a pyrimidine.
