Genetic Code
The instructions in a gene that tell the cell how to make a specific protein.
The genetic code can be expressed as either RNA codons or DNA codons. RNA codons occur in messenger RNA (mRNA) and are the codons that are actually "read" during the synthesis of polypeptides (the process called translation).
genetic code The linear series of nucleotides, read as triplets, that speci?es the sequence of amino acids in proteins. Each triplet speci?
genetic code
The system of nucleotide triplets in DNA and RNA that carries genetic information; referred to as a code because it determines the amino acid sequence in the enzymes and other protein molecules synthesized by the organism.
Genetic code
The assignment of each of the triplet codons of mRNA to amino adds and translation stop signals. See Codon table.

The genetic code is the correspondence between the triplet of bases in dna with the amino acids. The discovery of the genetic code clearly ranks as one of the premiere events of what has been called the golden age of biology (and Medicine).
The genetic code was broken by Marshall Nirenberg and Heinrich Matthaei, a decade after Watson and Crick's work.

Degeneracy Backtranslation of amino acid sequences usually leads to a collection of possible base sequences which can code for the amino acid sequence, due to the degeneracy of the genetic code.
associated genetic codes has increased dramatically over the past few
decades, we still have a long way to go. Due to their tremendous
capabilities, new strains are emerging and other strains are
re-emerging.
They translate the genetic code from the molecular language of nucleic acid to that of amino acids-the building blocks of proteins. Proteins are the molecules that perform all the functions of cells and living organisms.
Coding genes map into proteins using the genetic code. The genetic code is redundant (the technical term is degenerate), i.e., different triplets of nucleotides will produce the same amino acid.
There are 6 codons in the genetic code for arginine, yet, although this large a number of codons is normally associated with a high frequency of the particular amino acid in proteins, arginine is one of the least frequent amino acids.
The process in which the genetic code carried by mRNA directs the synthesis of proteins from amino acids. The mRNA base sequence is translated into sequence of amino acids in a peptide or protein. Occurs on ribosomes. (Cf. transcription).
The genetic code is degenerate because there are many instances in which different codons specify the same amino acid. A genetic code in which some amino acids may each be encoded by more than one codon.

Degeneracy: A feature of the genetic code. More than one nucleotide triplet can code for the same amino acid. The same applies to the termination signal, which is encoded by three different stop codons.

The bases are the "letters" that spell out the genetic code. In DNA, the code letters are A, T, C, and G, which stand for the chemicals adenine, thymine, cytosine, and guanine, respectively.

It duplicates its DNA and the two new cells (daughter cells) have the same pieces and genetic code. Two identical copies come from one original. Start with one; get two that are the same. You get the idea.
SILENT MUTATION - A nucleotide substitution (never a single deletion or insertion) which does not alter the amino acid sequence of an encoded protein due to the degeneracy of the genetic code.
[22] Biologists generally regard the universality of the genetic code as definitive evidence in favor of the theory of universal common descent for all bacteria, archaea, and eukaryotes (see: origin of life).[23] ...
Chromosome: rod-shaped bodies in the nuclei of cells that consist of a string of genes and maintain the structure or arrangement of the genetic code (DNA).
