GENE SEQUENCING Meaning and
Definition
-
Gene sequencing is a technique used to determine the precise order of nucleotides in a DNA molecule. It involves the process of reading the chemical composition of a DNA strand to decipher the genetic information encoded within an organism's genome. Identifying the order of nucleotide bases - adenine (A), thymine (T), cytosine (C), and guanine (G) - in a DNA sequence allows researchers to understand and analyze the structure, function, and evolution of genes.
Gene sequencing typically occurs in specialized laboratories using advanced technologies and computational tools. The process starts with extracting DNA from a sample, often obtained from blood, saliva, tissues, or cells. The DNA is then amplified to create multiple copies for analysis. Several methods can be employed for gene sequencing, including Sanger sequencing, next-generation sequencing (NGS), and more recently, third-generation sequencing platforms.
Gene sequencing has revolutionized various fields, such as medicine, agriculture, and evolutionary biology. In medicine, it enables the identification of genetic variations associated with diseases, aiding in the diagnosis, treatment, and prevention of genetic disorders. In agriculture, gene sequencing is used to improve crops through the identification of desirable traits and the development of genetically modified organisms. Additionally, sequencing genes has allowed scientists to understand the evolutionary relationships between species, contributing to our understanding of biodiversity and the history of life on Earth.
In summary, gene sequencing is a powerful tool that unravels the genetic information contained within a DNA molecule, enabling researchers to explore and understand the intricacies of genes and genomes.

Etymology of GENE SEQUENCING
The term "gene sequencing" has its roots in two words: "gene" and "sequencing".
1. "Gene": The word "gene" originated in the early 20th century and is derived from the German word "Gen", coined by Danish botanist Wilhelm Johannsen in 1909. Johannsen used the term to refer to the hereditary units that carry biological information from parents to offspring. It is believed that the term was inspired by the Greek word "genesis", meaning "origin" or "formation".
2. "Sequencing": The word "sequencing" is derived from the Latin word "sequens", which means "to follow" or "sequence". The term was originally used in various fields to describe the process of arranging or following a specific order of items, events, or actions.
