DNA full form in biology

DNA full form in biology: Deoxyribonucleic acid.

Above all, DNA is the hereditary element of a living cell. It is found in each and every living organism. Inside each and every living cell. It contains all the information about the genes. That is present in a living organism. Genes are passed from one generation to the other. Like, from parents to their children. The DNA is found in the nucleus of the cell. However, the genes are like instructions. Coded on it. Moreover, genetic information is stored. In the form of four nitrogen bases. That are: Adenine (A), Cytosine(C), Guanine(G) and Thymine (T). These base pairs form the rungs in a single DNA.

According to lunadna.com, DNA was discovered by a biochemist - named Fredrich Miescher. He was a resident of Switzerland. It was discovered in the year of 1869. However, after a lot of researches, studies and efforts. It took more than 78 years. To get its importance discovered. DNA is important. As it promotes the characteristics of the parent. To its children. But advanced biology is doing endless experiments and researches. To find out its importance, even after a period of 145+ years. However, knowing the DNA full form in biology is worth it.


DNA is observed. To have the shape of a double helix. It looks similar to the shape of a twisted ladder. The two longer sides are made of nucleotide strands. They are known to be made of sugar and phosphates. However, the nitrogen bases are the rungs. Moreover, the rungs are made of a pair of nitrogen bases. These rungs are responsible to hold the two long strands together. Therefore, nitrogen bases, sugar and phosphates. All three are required to form the DNA. Giving it a microscopic shape of a twisted ladder.

Human beings are known to have. A unique kind of DNA. It is known to be made of. About 3 billion + base pairs. (Pairs of A, C, G or T). But experiments and observations. States that about ninety-nine per cent. Of those base pairs are found the same. In each and every human being. Moreover, these bases are found in a particular sequence. And the sequence represents the kind of information. That is stored in it. The sequence of the rumps, i.e. the base pairs. However, they tell us the kind of information stored in the DNA. They are, however, found to be same and unique. In almost, every human being's body.


The structure of the DNA is easy to understand. Just look at the below image. Provided by projectmine.com. Moreover, it is a kind of distorted microscopic image of the DNA. One can see, a kind of X-ray image. Imagine it as a twisted ladder. Having two sections. Along, with seven rumps in each section. Supporting the long strands. So, the long strands are made of sulphate and phosphorus. However, the rumps are made of nitrogen bases. They seem to be joined with two tiny parts. 

Moreover, each of this part. Represents a nitrogen base. Moreover, two of them makes the nitrogen base pair. Just consider those pairs as similar to the pairs of alphabets. However, knowing the DNA full form in biology is worth it.


Being a nucleic acid, DNA is found in the nucleus. Of each and every cell of a living organism. DNA is used to promote genes. It contains crucial genetic information. That is passed from one generation to the other. However, the DNA remains tightly winded upon the nucleus. Consequently, it forms chromosomes. However, these chromosomes help the DNA molecules. To stay in position and with proper alignment.

DNA and RNA are terms. That is heard side by side. Actually, DNA works by copying itself. Into that single strands. Made of nitrogen bases. These single-stranded molecules are called the RNAs. And they are very essential for the DNA structure to exist. However, RNA actually translates the data encoded in the DNA. In the meantime, the DNA unwinds its tight grasp. As it is the moment its data is being copied. RNA works as a translator as well as a promoter. It carries genetic information from DNA. Then passes it through ribosomes. And ends up creating proteins. That is finally, turned into the birth of a new living organism.


Trait: he distinguishable physical and non - physical characteristics of a living being is called a trait. Physical characteristics include hair colour, skin colour, face colour, height and stuff like that. However, non - physical characteristics include. Inbuilt diseases, emotions, behaviour, attitude and other stuff like that. They are within a living being's body.

Inheritance: The passing of genetic data from parents to their young ones. Is known as inheritance. Traits are inherited. However, a lot of examples of inheritance can be seen in our daily life. Like, like a particular thing is not inherited. However, it is happening after the birth. However, being strong, or tall is inherited.

Pedigree: The trait flowchart. It is actually a tree cum flowchart. That clearly depicts. About the method, how - one trait is passed from one generation to the next. A flow chart, explaining. How a trait is being passed within a family tree.

Diploid: It refers to something double. In biology, it refers to having two copies of each chromosome. Human beings have two copies of twenty-three different chromosomes. That totals to forty-six copies. For an average human being, most of the human cells are found to be diploid.
