DNA Full Form – What Is DNA, Definition, Meaning, Uses

DNA Full Form Friends, in this article, we’ll look at the full form of the DNA. The age of science is currently in effect. With the passage of time, science has progressed to the point that it can now answer any problem. The tiniest item has been discovered thanks to modern science. Science is doing the work of invention by performing every successful test. Through science in man, enormous advancements have been made in many domains today, from space to human health.

DNA Full Form 

DNA’s full form is “Dioxyribo Nucleic Acid.” These are filamentous molecules that can be discovered in living cells’ chromosomes. Living cells are linked to DNA. It has the shape of a wavy ladder, which is visible through the 3D structure. DNA consists of two strands. Its structure is made up of these filaments, which together create a curved structure known as DNA.

Who invented DNA?

  • Gregor Mendel, who was later dubbed the “Father of Genetics,” discovered the basic principle of genetics, namely heredity, in 1866.
  • Friedrich Mischer, a Swiss physical chemist, discovered the first DNA three years later, in 1869. DNA, which was a completely new chemical at the time, was the first to be discovered, and its importance to life remained unknown.
  • According to Live Science, Francis Crick, James Watson, Maurice Wilkins, and Rosalind Franklin did not discover the structure of DNA that we know today as a double helical polymer until 1953.
  • The discovery is a significant step forward in physiology and medical science because it explains how information is transferred from a microscopic particle to a living organism.
  • The Nobel Prize in Physics was awarded to Francis Crick, James Watson, and Maurice Wilkins in 1962 for their discoveries.

What is the DNA structure? 

DNA is found on each chromosome. It is made up of four bases: adenine, thymine, guanine, and cytosine, as well as a sugar residue, termed deoxyribose. There are an endless number of distinct combinations of these four bases in the entire genetic code — that is, each human gene.

DNA is made up of two chains made up of bonds between nucleotides or phosphates, sugars, and nitrogenous bases, according to Watson, Crick, Wilken, and Franklin.

Nucleotide molecules in the form of sugars and phosphates link together to create the double helix, two long spiral strands of DNA. As a backbone, the nitrogenous base sugars are covalently bonded to the phosphate molecule.

Adenine, thymine, guanine, and cytosine are nucleotide compounds that contain a phosphate group and a nitrogenous base. The nitrogenous base adenine will only bind to the nitrogenous base thymine, whereas cytosine will only bind to the nitrogenous base guanine.

According to Live Science, the DNA strand is so lengthy that it must be coiled in order to enter the cell as chromosomes. A human cell’s nucleus includes 23 pairs of chromosomes that govern how features are passed down.

Why is DNA required?

DNA is passed down through the generations in an encrypted (coded) form that carries genetic information. It is an essential component of living beings, as there is no life without DNA. Gender, hair, and eye color are all determined by genetic information stored in a sequence of individual bases. It is comparable to the letters that make up a person’s name. This information is conveyed by creating identical copies of DNA during reproduction or cell growth.

What exactly is RNA? 

Ribonucleic acid (RNA) is a type of genetic material that is made up of nucleotides. RNA is a genetic information carrier that is also involved in the creation of many proteins in the human body.

DNA is the transporter of genetic information in all living organisms. It preserves information about each living being’s blueprint, such as gender, hair color, and eye color. This function is performed by RNA in some viruses.

RNA has a variety of tasks in addition to delivering genetic information. It can, for example, transfer information for protein creation or operate as an activator (ribozyme), much like an enzyme.

What exactly is the distinction between DNA and RNA?

Ribonucleic acid, sometimes known as RNA, is a single-chain polynucleotide. The genetic code in the virus is carried by RNA rather than DNA. Explain the distinction between DNA and RNA.


The nucleus or nucleus of the cell, as well as the fluid of the nucleoid, contain DNA, whereas RNA is found in the cytoplasm, nucleus, and ribosomes. RNA, on the other hand, can leave the nucleus but DNA cannot.

Chain length:

DNA is shaped like a double helix, with two interlocking chains, whereas RNA only has one chain or helix. In comparison to DNA, RNA has a very small number of nucleotide chains.

Component of sugar:

DNA has a 2-deoxyribose sugar-phosphate backbone, whereas RNA has a ribose sugar-phosphate backbone. Because ribose has a -OH group, it is more reactive than deoxyribose, making RNA unstable in bases. This means that RNA is susceptible to enzyme attack and, unlike DNA, cannot be safeguarded for lengthy periods of time.

Techniques (DNA Vs RNA):

DNA is responsible for storing and transmitting genetic information over lengthy periods of time. For the production of proteins, RNA acts as a carrier and translator of genetic information. RNA suppresses tumor or cancer growth by inhibiting gene expression.

Damage from Ultraviolet:

DNA is more vulnerable to UV light damage than RNA, which is more robust.


DNA, on the other hand, can replicate itself with the help of the enzyme DNA polymerase, whereas RNA cannot. When RNA is needed, consumed, and recycled, it is created by DNA with the help of the RNA polymerase enzyme.
