GENE CODING Meaning and
Definition
-
Gene coding refers to the process by which specific sequences of DNA, known as genes, are translated into functional proteins or other types of molecules within a living organism. Genes contain the genetic information required to synthesize proteins and play a fundamental role in determining the characteristics and functionality of an organism.
The genetic code is composed of a sequence of nucleotides, which are the building blocks of DNA. Each nucleotide consists of a sugar, a phosphate group, and one of four nitrogenous bases - adenine (A), cytosine (C), guanine (G), and thymine (T). The sequence of these bases in a gene determines the order in which specific amino acids are assembled to form a protein.
During the process of gene coding, the DNA sequence is first transcribed into a molecule called messenger RNA (mRNA) by an enzyme called RNA polymerase. The mRNA carries the genetic information from the DNA in the nucleus to the ribosomes in the cytoplasm, where protein synthesis occurs. At the ribosomes, the mRNA sequence is decoded in sets of three nucleotides, known as codons, by transfer RNA (tRNA) molecules. Each codon corresponds to a specific amino acid, and the tRNA brings the corresponding amino acid to the ribosome. As the ribosome moves along the mRNA, it joins the amino acids together, forming a chain that folds into a three-dimensional protein molecule.
In summary, gene coding is the process by which the information stored in genes is read and translated into functional proteins or molecules, ultimately determining the characteristics and functions of an organism.

Etymology of GENE CODING
The term "gene coding" does not have a specific etymology, as it is a combination of two different terms in genetics: "gene" and "coding".
The word "gene" was coined by the Danish scientist Wilhelm Johannsen in 1909, derived from the German term "gen" meaning "gene" or "pangenesis" proposed by Charles Darwin. It was used to describe a hereditary unit that carries genetic information and is responsible for the transmission of traits from parents to offspring.
The term "coding" in the context of genetics refers to the process of encoding genetic information in the form of DNA or RNA sequences. It involves the specific sequence of nucleotides that carries the instructions for building and maintaining an organism.
When combined, "gene coding" refers to the process of encoding genetic information within a gene. It describes how DNA or RNA sequences provide instructions for the synthesis of proteins or functional RNA molecules.
