Sequencing
Sequencing
Sequencing (pronunciation: /ˈsiːkwənsɪŋ/) is a process used in various fields, including genomics, bioinformatics, and molecular biology, to determine the order of nucleotides in DNA or RNA, or of amino acids in proteins.
Etymology
The term "sequencing" comes from the Latin sequi, meaning "to follow". In the context of genomics and molecular biology, it refers to the process of determining the precise order of nucleotides within a DNA molecule.

- Bioinformatics: An interdisciplinary field that develops methods and software tools for understanding biological data, particularly when the data sets are large and complex.
- Molecular Biology: The branch of biology that deals with the structure and function of the macromolecules essential to life.

- DNA: Deoxyribonucleic acid, a self-replicating material present in nearly all living organisms as the main constituent of chromosomes. It is the carrier of genetic information.
- RNA: Ribonucleic acid, a nucleic acid present in all living cells. Its principal role is to act as a messenger carrying instructions from DNA for controlling the synthesis of proteins.
- Protein: A large molecule composed of one or more chains of amino acids in a specific order; the order is determined by the base sequence of nucleotides in the DNA coding for the protein.
