What is the Difference between D.N.A. and R.N.A

Difference between D.N.A. and R.N.A :: One of the most significant subtlest parts of cell biology is D.N.A. and R.N.A. Form both of these. We can know the genetic information. Both of them belong to the linear polymer category.

D.N.A. and R.N.A. are made of sugar and phosphate. Despite having too many similarities, there are a few differences between D.N.A. and R.N.A, although both of them function together and accomplish their preface.

Here, we will discuss in detail about the critical difference between D.N.A. and R.N.A. Let’s have a look in the article to know more about D.N.A. and R.N.A.

D.N.A. Definition:

The full form of D.N.A. is Deoxyribonucleic acid. The location of the D.N.A. is mainly the nucleus. We can get some quantity of D.N.A. in mitochondria. Its structure is a long ladder type that is a double helix. For reproducing cells, protein, metabolism, D.N.A. is essential.

Most of the time, D.N.A. is nucleotides’ double-standard polymer. But there is one-standard D.N.A. also. These nucleotides are a form of deoxyribose sugar, phosphate, and nitrogenous. We can see that there are four kinds of nitrogenous base D.N.A. available.

These four types are adenine, guanine, thymine, and cytosine. The base of nitrogenous creates a ladder’s rungs. Whereas the phosphate and the deoxyribose sugars combined develop a structure of back-bone.

D.N.A. gathers all the information that is essential for building and controlling the cells. The transfer of this information from the primary cells to other cells is known as vertical gene transfer.

 During the process of D.N.A. reiteration, it seems to happen. If one of the cells creates a similar imitation of its D.N.A., then D.N.A. will replicate. At that time, the cells start distributing the appropriate copy of D.N.A. according to the battery. Although D.N.A. does not create the structure of cells, D.N.A. can work as the emergence of nucleosides and nucleotides.

If we talk about the types of D.N.A., there are mainly three kinds of D.N.A. The main structure of D.N.A. is the double standard. These three types of D.N.A. are A-form D.N.A., B-form D.N.A., and Z-form D.N.A. Let’s have a brief discussion about these types.

●    A-DNA: This is a right-handed double helix form of D.N.A. It has a few similarities with the B-DNA form.

●    B-DNA: It is the most usual D.N.A. form. It is a right-handed helix. Most of the people who belong to the standard psychological state have this kind of D.N.A.

●    Z-DNA: Although it is a left-handed D.N.A., it plays a vital role in generic regulations.

There are other kinds of D.N.A. These are –

● Chromosomal D.N.A. (nuclear D.N.A.)

● Extrachromosomal (plasmid D.N.A., mt- D.N.A., Chl- D.N.A., etc.)

Functions Of D.N.A.

● storing genetic information

● Directs protein synthesis

● Determines genetic coding

● plays a vital role in any metabolic activities, evolution,

● Functions a key role in heredity.


The full form of R.N.A. is ribonucleic acid. The main component of R.N.A. is ribose nucleotides and phosphate. The nitrogenous R.N.A. are adenine, guanine, cytosine, and Uralic. R.N.A. helps in protein implication. In comparison with D.N.A., R.N.A. carries essential genetic information.

R.N.A. belongs to the category of a single-stranded biopolymer. R.N.A. has a three-dimensional form. This form helps to modify the sugar and the nitrogenous bases in a few ways. This type of modification helps to form the chemical bonds.

The weakly structured molecules are easily destroyable. Mainly there are three kinds of R.N.A., and the role of these three types is different. The purpose of Messenger R.N.A. is serving the temporary implications of D.N.A. Ribosomal R.N.A. helps to create protein structure or ribosomes.

The Transfer R.N.A. serves amino acids for creating the formation of protein. Let’s look at the full form of these three kinds of R.N.A., and it’s the primary function.


● Messenger R.N.A. (mRNA)

● Transfer R.N.A. (tRNA)

● Ribosomal R.N.A. (rRNA)

Functions of R.N.A.:

● Transferring genetic information from the D.N.A. to proteins

● carrying it outside the nucleus

● translating it to proteins

Difference between D.N.A and R.N.A

Difference between D.N.A and R.N.A
Its full form is Deoxyribonucleic Acid.Its full form is Ribonucleic Acid.
The location of the DNA is mainly nucleus and Mitochondria.RNA forms in the nucleus and moves in the cytoplasm.
Here the nucleotides are A (adenine), G (guanine), T (thymine), or C (cytosine).RNA contains Uracil in place of thymine.
Here, the chain of nucleotides is long.Here, the chain is relatively strong.
DNA always presents in the nucleus.RNA can leave the nucleus.
It is less versatile than RNA.It is more versatile than DNA.
It gives strong genetic information.RNA transfers the information from DNA to Protein.


We hope, this above information about DNA and RNA will help you to know about genetic matters. Now you know not only the functions of them. But also you attain more knowledge about the difference between DNA and RNA. 

FAQS on Difference between dna and rna

What are the main functions of RNA?

The central source of molecular biology says that the main purpose of RNA is to change knowledge saved in DNA into proteids. In fact, there is more extra to RNA.

What is the role of RNA?

Cells use RNA for several tasks, one of which is called messenger RNA or mRNA. It is a nucleic acid information molecule that transfers information from the genome to the protein by translation.

Do viruses have DNA?

Most viruses use RNA or DNA as genetic material. Nucleic acids can be single-stranded or double-stranded. The entire infectious viral particle (also known as a virion) comprises a nucleic acid and a protein shell.

How much DNA is a chromosome?

In humans, each cell typically contains 23 pairs of chromosomes, for a total of 46 chromosomes. The 22nd chromosome (also known as the autosomal) is the same in males and females. The 23rd sex chromosome is male and female.

What type of virus is a DNA virus?

DNA viruses contain essential pathogens such as herpes virus, Baliora virus, adenovirus, and papillomavirus.
