The full form of DNA is:
deoxyribonucleic acid
Understanding the Full Form of DNA
The question asks for the full form of the acronym DNA. DNA is a fundamental molecule found in all living organisms. It carries the genetic instructions for the development, functioning, growth, and reproduction of all known organisms and many viruses.
Let's break down the meaning of the letters in DNA:
- D stands for Deoxyribo
- N stands for Nucleic
- A stands for Acid
Putting these parts together gives us the full form.
Analyzing the Options for DNA Full Form
Let's look at the provided options and see which one correctly represents the full form of DNA:
- Option 1: deoxyribeneutral acid - This option is incorrect. The 'neurtal' part is wrong.
- Option 2: deltanucleic acid - This option is incorrect. The 'delta' part is wrong.
- Option 3: deoxyribonucleic acid - This option correctly spells out the full form of DNA.
- Option 4: dyoxyenucleic acid - This option is incorrect. The spelling of 'deoxyribo' is wrong.
Based on the components of the DNA molecule, the correct term is 'deoxyribonucleic acid'. This name comes from the sugar molecule present in DNA, which is deoxyribose, and its acidic nature due to the phosphate groups.
Correct Full Form of DNA
The full form of DNA is deoxyribonucleic acid. This molecule contains the genetic code that determines the inherited traits of an organism.
Therefore, the option that states 'deoxyribonucleic acid' is the correct answer.

Additional Information on DNA Structure and Function
DNA is a polymer, meaning it is a large molecule made up of repeating smaller units called monomers. The monomers of DNA are called nucleotides.
Each DNA nucleotide consists of three parts:
- A deoxyribose sugar molecule.
- A phosphate group.
- One of four nitrogenous bases: Adenine (A), Guanine (G), Cytosine (C), or Thymine (T).
In DNA, two polynucleotide strands coil around each other to form a double helix structure. The bases pair specifically: Adenine always pairs with Thymine (A-T), and Cytosine always pairs with Guanine (C-G). This base pairing is crucial for DNA replication and protein synthesis.
The sequence of these bases along the DNA strand constitutes the genetic code, which provides instructions for building and maintaining an organism.
