The relationship between nucleotide sequence and amino acid sequence is called the genetic code.- - -In those segments of DNA that carry information about proteins, the sequence of the nucleotides determines the sequence of amino acids in a polypeptide chain (one chain of a protein).A group of three consecutive nucleotides codes for (represents) one amino acid. This group is called a codon.The different amino acids are coded for by different codons. What each of the 64 codons stands for is the genetic code.Three of the codons mean STOP; each of the 61 others stands for one of the 20 amino acids. In addition, one of the codons does double duty: it means START when it appears in a particular position.The coding sections of DNA are called genes. Some genes code for RNA (such as transfer and ribosomal RNA); polypeptide chains are coded for by other genes, or, more specifically, exons of those genes. The exons are often separated by introns, which, although consisting of a sequence of nucleotides, do not code for amino acids.The idea that nucleotide sequence (often referred to as base sequence) might code for amino acid sequence followed the proposal of the double-helix structure for DNA in 1953.In 1958 Francis Crick gave the name sequence hypothesisto the idea that the nucleotide sequence corresponded to the sequence of amino acids in the chain to be synthesized. (For some reason this name is not well known now, and is often confused with Crick's term "central dogma", which, as Crick used it, denotes a different concept.)In 1961 there were two important breakthroughs. Crick and Sydney Brenner showed that the code consisted of "triplets" (Brenner coined the word codon the following year), and Marshall Nirenberg and Heinrich Matthaei developed a technique for working out the code (in its messenger RNA version).By 1966 all the 64 possible codons had been worked out.
"Specific"
Molecular bases
The genetic code is determined by the specific sequence of four nucleotide bases that make up DNA. The bases are guanine, adenine, thymine, and cytosine.
Nucleotide sequence, human, hemoglobin
Yes, DNA carries the instructions for the correct sequence of nucleic acids in a protein. These instructions are encoded in the DNA molecule as a specific sequence of nucleotide bases (adenine, thymine, cytosine, and guanine). Through a process called transcription, the DNA sequence is transcribed into a messenger RNA (mRNA) molecule, which is then translated into a specific sequence of amino acids to form a protein.

tRNA
Well its not ribersome supposed to be ribosome. Ribosome is an an organelle (an internal component of a biological cell) the function of which is to assemble the twenty specific amino acid molecules to form the particular protein molecule determined by the nucleotide sequence of an RNA molecule.
Cells can synthesize specific proteins because the sequence of nucleotide bases in the DNA of genes specifies a particular sequence of amino acid building blocks of a protein molecule. This correspondence of gene and protein building block sequence is called the genetic code.
a specific nucleotide sequence in DNA that signals a stop to transcription
A cluster of three nucleotides is called a 'codon' - However, the term is only really used to refer to refer to a 3 nucleotide sequence on an mRNA molecule. Codons provide a means by which charged tRNA molecules can specifically add amino acids to a growing polypeptide chain. tRNA molecules have the complementary 3 nucleotide sequence (anticodon) that allow the specific recognition.
