The DNA full form is Deoxyribonucleic Acid. DNA is a set of molecules responsible for the transmitting and carrying the inherited materials or genetic instructions from parents to children. DNA is an organic compound that has a unique molecular structure. It is found in eukaryotic and prokaryotic cells. The Swiss biologist Johannes Friedrich Mistier first recognized and named DNA in 1869, during his work on white blood cells. The double helix structure of a molecule of DNA was later discovered by James Watson and Francis Crick using experimental evidence. Finally, it has been shown that DNA is responsible for processing a human being’s genetic information.
The DNA structure can be thought of as a twisted ladder. This structure is described as a double-helix, as illustrated in the figure above. It is a nucleic acid, and all nucleic acids are made up of nucleotides. The DNA molecule is composed of units called nucleotides, and each nucleotide is composed of three different components such as sugar, phosphate groups and nitrogen bases.
The basic building blocks of DNA are nucleotides, which are composed of a sugar group, a phosphate group, and a nitrogen base. The sugar and phosphate groups link the nucleotides together to form each strand of DNA. Adenine (A), Thymine (T), Guanine (G) and Cytosine (C) are four types of nitrogen bases.
DNA full form is the genetic material which carries all the hereditary information. Genes are the small segments of DNA, consisting mostly of 250 – 2 million base pairs. A gene code for a polypeptide molecule, where three nitrogenous bases sequence stands for one amino acid. Polypeptide chains are further folded in secondary, tertiary and quaternary structures to form different proteins. As every organism contains many genes in its DNA, different types of proteins can be formed. Proteins are the main functional and structural molecules in most organisms. Apart from storing genetic information, DNA full form is involved in:
Replication process: Transferring the genetic information from one cell to its daughters and from one generation to the next and equal distribution of DNA during the cell division
Mutations: The changes which occur in the DNA sequences, Transcription, Cellular Metabolism, DNA Fingerprinting, Gene Therapy.
DNA replication is an important process that occurs during cell division. It is also known as semi-conservative replication, during which DNA makes a copy of itself.
DNA replication takes place in three stages:
The replication of DNA begins at a point known as the origin of replication. The two DNA strands are separated by the DNA helicase. This forms the replication fork.
DNA polymerase III reads the nucleotides on the template strand and makes a new strand by adding complementary nucleotides one after the other. For eg., if it reads an Adenine on the template strand, it will add a Thymine on the complementary strand.
While adding nucleotides to the lagging strand, gaps are formed between the strands. These gaps are known as Okazaki fragments. These gaps or nicks are sealed by ligase.
The termination sequence present opposite to the origin of replication terminates the replication process. The TUS protein (terminus utilization substance) binds to terminator sequence and halts DNA polymerase movement. It induces termination.
A genetic disorder is a disease caused in whole or in part by a change in the DNA sequence away from the normal sequence. Genetic disorders can be caused by a mutation in one gene (monogenic disorder), by mutations in multiple genes (multifactorial inheritance disorder), by a combination of gene mutations and environmental factors, or by damage to chromosomes (changes in the number or structure of entire chromosomes, the structures that carry genes).
As we unlock the secrets of the human genome (the complete set of human genes), we are learning that nearly all diseases have a genetic component. Some diseases are caused by mutations that are inherited from the parents and are present in an individual at birth, like sickle cell disease. Other diseases are caused by acquired mutations in a gene or group of genes that occur during a person's life. Such mutations are not inherited from a parent, but occur either randomly or due to some environmental exposure (such as cigarette smoke). These include many cancers, as well as some forms of neurofibromatosis.
Biotechnology genetic engineering, the artificial manipulation, modification, and recombination of DNA or other nucleic acid molecules in order to modify an organism or population of organisms. The term genetic engineering is generally used to refer to methods of recombinant DNA technology, which emerged from basic research in microbial genetics. The techniques employed in genetic engineering have led to the production of medically important products, including human insulin, human growth hormone, and hepatitis B vaccine, as well as to the development of genetically modified organisms such as disease-resistant plants.
Genetic engineering has transformed healthcare by enabling gene therapy, accurate diagnosis of genetic disorders, and the development of personalized medicine. Gene therapy involves replacing faulty or missing genes with healthy ones to treat genetic diseases like cystic fibrosis or sickle cell anaemia. Diagnosing genetic disorders is now faster and more precise thanks to advanced DNA sequencing technologies, allowing for early detection and intervention. Personalized medicine, tailored to an individual’s genetic makeup, ensures effective treatments with minimal side effects, particularly in cancer therapies and rare genetic conditions. Additionally, genetic modifications are utilized to create vaccines, such as mRNA-based COVID-19 vaccines, highlighting their potential in addressing global health challenges. These advancements illustrate the transformative impact of genetic technology on improving health outcomes and enhancing quality of life. The fields of medicine and genetics continue to converge, opening doors to innovative treatments and preventive care solutions.
The forensic science unravelling the Mystery of the Criminal: With DNA Fingerprinting Since long DNA full form fingerprinting is described as the wonderfully reliable key to forensic science - a sure-fire means to catch criminals and solve cases. Using a person's unique genetic markers, forensic experts can match biological evidence from a crime scene-blood, hair or saliva-to those of potential suspects. There could even be no actual evidence minutely changed the very background of the investigation process in which the criminals can be brought to book, said special public prosecutor Ujjwal Nikam. DNA fingerprinting also goes a long way to exonerate the wrongly accused while solving cold cases and the discovery of justice long after the crime has been committed. It helps in identifying the dead in calamities and establishing a biological relationship for legitimate purposes. Because of its entireness and authenticity, the ACCURACY and RELIABILITY makes DNA fingerprinting an essential tool in modern forensic science, changing the real justice.
Evolutionary biology A method that evolutionary biology employs in its search for ancestry and evolution of different kinds. Scientists have relied upon the sequence comparisons of DNA full form to build an evolutionary history of those they have studied. This method of undergoing the evaluation points to shared ancestry having to do with genetics and the presence of common ancestors followed by the divergence point. Phylogeny is essentially constructing an evolutionary tree beyond how the species has adapted over time. In addition, these studies indicate genetic markers that speak to survival, and thus to evolutionary pressures and biodiversity.
Probably among the most innovative farming changes, genetic modifications have unlocked new opportunities in the genetic manipulation of plants in agriculture. Normally, such developments have been enabling the formation of disease-resistant and high-yield plant types. They entail taking genes primarily for defense of plants against diseases, severe climatic conditions, and nutrient deficits. These improvements are ultimately a great boon to food security or soft development of a healthier planet, as pesticides can be curtailed while sustainable farming continues. The future of agriculture is increasingly sculpted by genetic engineering on a global scale.
DNA full form, as the blueprint of life, are a central driving force in many aspects of science and the human quest for knowledge. From the time DNA was first recognized and its internal secrets opened up, it has changed significantly these fields: genetics and medicine, biotechnology; forensics; evolutionary biology; and agriculture. Detection of certain genetic diseases, the initiation of personalized medicine, carrying of the criminals using DNA fingerprinting, and improving agricultural produce through genetic engineering are some of the DNA uses with promising and far-reaching prospects. The capability to manipulate this molecule has opened new horizons, providing the promise of gene therapy. In the future, the altered crops could be resistance to different diseases, and visionary new vaccines could do away with some diseases in certain ways. As further research goes on, realization of the use of DNA full form in bringing about some global health, food security, and environmental sustainability issues becomes more and more evident. The effects of the research and possible applications could lead to the very compact and widely used DNA-special applications in science and society it enhances one understands of the continuing examination and ethical use of the genetic marvel.
