GENETIC CODE Meaning and
Definition
-
Genetic code refers to the biochemical instructions stored within the DNA and RNA molecules that determine the characteristics and functions of living organisms. It is the set of rules by which information encoded in DNA and RNA sequences is translated into the amino acid sequence of proteins. The genetic code is a universal language that allows the transmission of genetic information from one generation to the next.
The genetic code is composed of sequences of three nucleotide bases called codons. Each codon corresponds to a specific amino acid or a signal indicating the start or termination of protein synthesis. There are a total of 64 possible codons, representing the 20 different amino acids found in proteins. Some amino acids are specified by more than one codon, adding redundancy to the genetic code.
This code is highly conserved across all known organisms, which implies a common ancestry of all life on Earth. It is the fundamental mechanism through which genetic information is used to create and regulate the many complex processes that occur within cells.
Understanding the genetic code has enabled scientists to decipher the molecular basis of various genetic diseases and develop technologies to manipulate and modify genetic material through genetic engineering and gene therapy. It is a critical foundation for the field of genetics and plays a vital role in advancing our understanding of life's diversity and complexity.

Etymology of GENETIC CODE
The word "genetic code" comes from the combination of two terms: "genetic" and "code".
1. Genetic: The term "genetic" originated from the Greek word "genesis", meaning "origin", "birth", or "creation". It was first used in the late 19th century and initially referred to the study of heredity and the passing of traits from parents to offspring.
2. Code: The term "code" is derived from the Latin word "codex", which refers to a book or manuscript. It was first used in English in the early 14th century and originally denoted a system of laws or regulations. Over time, it began to be used in a broader sense to represent any systematic arrangement or set of rules.
