Nucleotides In RNA Structure: Comparative Analysis Across It

Nucleotides in RNA structure are the basic structural and functional monomers, better to say building blocks of nucleic acid. Let’s compare all nucleiotides in RNA structure and discuss each aspects regarding them. 

RNA or Ribonucleic acid is a single polynucleotide chain made up of nucleiotides. There are four different nucleotides found in RNA structure, such as –

Adenosine Monophosphate or AMP

Adenosine Monophosphate is one of the four nucleobases, made up of a ribose pentose sugar, a phosphate group and nucleobase Adenine. The adenine of AMP is a Purine base and forms hydrogenous double bonds with Uracil of UM which increases stability.

The adenine of AMP makes the poly A tail of RNA means the RNA contains multiple Adenine residue at the end. The AMP can be converted into ADP or ATP as the energy source of a cell. As Cyclic AMP, it also controls hormone regulation in cells.

Guanosine Monophosphate or GMP

Guanosine monophosphate is one of the four nucleotides in RNA structure, typically comprising a five- carbon  ribose sugar, a phosphate group and nucleobase Guanine in it. Guanine is a purine base and makes hydrogenous triple bonds with Cytosine of CMP molecules.

It is an important monomer in RNA structure. In the 5-prime end of RNA modified GMP or Guanine sequence makes the 5-prime cap which is important to protect the nucleic acid and helps RNA processing and translation process. The GMP also plays a significant role in signal transduction and hormone regulation process.

Cytidine Monophosphate or CMP 

Cytidine Monophosphate is also a basic monomeric unit of RNA. It has three components, such as a ribose sugar, a phosphate group and nucleobase cytosine. Cytosine is a pyrimidine base , pairs with the Guanine of GMP by forming hydrogenous triple bonds. In signal transduction the role of CMP is immense.

Uridine Monophosphate or UMP

Uridine Monophosphate is a monomer nucleotide in RNA structure. It is a Nucleotide which is only found in RNA, absent in DNA structure. It is composed of three subunits, such as a ribose sugar, a phosphate group and nucleobase Uracil. The Uracil is a derivative of Thymine, which makes hydrogenous double bonds with adenine. UMP also plays a crucial role in glycogen synthesis.

These four nucleotides in RNA structure bind with each other, decoding specific sequences making the whole nucleic acid.As there are different kinds of RNA molecules present to perform different cellular activities, the nucleotides are arranged in them according to their type and support their specific functions.

Where are nucleotides found in RNA?

The nucleotides are the building blocks which associate in a specific manner, constructing the whole polynucleotide RNA strand. 

The phosphate of one nucleotide binds with other sugar, making the sugar phosphate backbone of nucleic acid. Though the RNA is a single stranded structure, some complementary bases eventually come in close contact and pairs construct a hairpin loop. These structural properties including base pairing, brings stability and enhances efficiency of RNA molecules.

What nucleotides are used in RNA?

There are four nucleotides used in RNA, such as Adenosine Monophosphate (AMP), Guanosine Monophosphate (GMP), Cytidine Monophosphate (CMP) and Uridine monophosphate (UMP).

What nucleotide is found in RNA and not DNA?

DNA and RNA both nucleic acids are made up of predominantly the same nucleotide units, except one.

The nucleotide Uridine monophosphate or UMP is present in RNA, not in DNA. Because the nucleobase Uracil is only present in RNA, in DNA it is present in its methylated version that is called Thymine. The nucleotide made up of Thymine is called Thymidine Monophosphate.

What is the Role of Nucleotides in Protein Synthesis?

Nucleotides play a crucial role in the protein synthesis process. During translation, ribosomes read mRNA molecules, composed of nucleotides, to assemble amino acids into a polypeptide chain. Nucleotides also serve as the building blocks of DNA and RNA, storing and transmitting genetic information necessary for proper protein synthesis.

How are the nucleotides arranged in RNA?

The nucleotides in RNA structure are arranged in a specific manner. 

Nucleotides which decodes genetic information for protein synthesis by forming codons, are present in the middle of the strand. At the 5′ end, Guanines are arranged, making the 5′ cap that gives protection. At the 3′ end or tail position several Adenosine Monophosphates are attached, making the poly A tail of RNA to protect shortening.

Composition of nucleotides in RNA?

Nucleotides are generally an ester between nucleosides and phosphoric acids.

Every nucleotide has a five carbon ribose sugar moiety, a phosphate group and one of the four nucleobases in its structure. The four nucleobases are Adenine (A), Guanine (G), Cytosine (C) and Uracil (U).

The Adenine and Guanine are purine bases. Cytosine and Uracil are pyrimidine bases.
