The term "coding sequence" refers to a specific segment or part of DNA (deoxyribonucleic acid) that is responsible for encoding proteins. This means that the genetic information contained within this particular region of DNA will be used by cells to create and produce functional proteins, which are essential for various biological processes such as growth, development, metabolism, and repair.
In other words, a coding sequence provides instructions for building a protein molecule, specifying which amino acids should be combined in what order to form the final protein product. This process occurs through a complex cellular machinery that reads the genetic code stored within the DNA and translates it into a specific sequence of amino acids, ultimately creating a functional protein.
Overall, the term "coding sequence" is an important concept in understanding how genes work to produce proteins, which are vital for life's functions at both the cellular and organismal levels.
