DNA SEQUENCING Meaning and
Definition
-
DNA sequencing is a laboratory technique used to determine the precise order of nucleotide bases in a given DNA molecule. It provides valuable insight into the genetic makeup of an organism and allows for the identification and study of specific genes and their functions. DNA sequencing is a fundamental tool in the field of genetics and has contributed significantly to advancements in medicine, agriculture, and biotechnology.
The process of DNA sequencing involves several steps. First, the DNA molecule of interest is extracted from cells and purified. Next, the DNA is replicated through a process called polymerase chain reaction (PCR) to obtain multiple copies. These copies are then subjected to a sequencing reaction, which usually employs a technique known as Sanger sequencing or more modern methods such as next-generation sequencing. DNA sequencing machines use various chemical and enzymatic reactions to read the sequence of bases in a DNA strand, typically represented by the letters A, T, C, and G, which represent the nucleotide bases adenine, thymine, cytosine, and guanine, respectively.
The resulting sequence data is then processed using computational algorithms to assemble the sequence reads and generate a DNA sequence. This sequence can be compared to existing databases to identify genes, study genetic variations, or determine the presence of certain mutations or diseases. DNA sequencing has revolutionized many scientific fields, including genomics, evolutionary biology, forensics, and personalized medicine, by providing a wealth of information that helps researchers understand and manipulate DNA for various applications.

Etymology of DNA SEQUENCING
The term "DNA sequencing" originates from the field of genetics and molecular biology.
The acronym "DNA" stands for deoxyribonucleic acid, which is the genetic material that carries the instructions for the development and functioning of all living organisms.
The word "sequencing" in this context refers to the process of determining the precise order of nucleotides (adenine, cytosine, guanine, and thymine) within a DNA molecule. By determining the exact sequence of nucleotides, scientists can analyze and understand the genetic information contained within a particular DNA sample.
Overall, the term "DNA sequencing" combines the concept of DNA, the molecule being studied, with the process of sequencing, which is the method used to determine its order of nucleotides.
