A sequence of three nitrogen bases, called a codon, codes for a single amino acid.
The gene within a chromosome contains the specific sequence of nucleotides that codes for the amino acid sequence of a protein. This gene is transcribed into messenger RNA (mRNA), which is then translated into a specific sequence of amino acids during protein synthesis.
A DNA codon is a three-nucleotide sequence that codes for a specific amino acid. It is the basic unit of the genetic code and is read during the process of protein synthesis to determine the correct sequence of amino acids in a protein.
When a gene is transcribed there is a sequence of RNA bases that was copied from the DNA sequence. The RNA sequence can be exactly the same as the DNA or can be modified more in higher organisms by removing the introns if any. Three RNA bases is a codon. Each codon signifies an amino acid. There is an initiation codon and a terminal codon. So the amino acid sequence is determined by the sequence (multiple of 3 RNA bases) of codons between the initiation codon and termination codon.
The primary structure of a protein is the sequence of amino acids in the protein. This is determined by the sequence of bases in the DNA ie by the genetic code. Each group of three bases in DNA codes for one amino acid in the protein ie it is a triplet code.
The DNA sequence TCAGCCACCTATGGA codes for the mRNA sequence UCAGCCACCUAUGGA, which translates to the amino acids Serine-Alanine-Threonine-Tryptophan. Therefore, this DNA sequence codes for 4 amino acids.
The sequence of basis on the DNA molecule is what directs the sequence of amino acids in the protein molecule - that's how it all links together! So, the sequence of bases in DNA codes for the sequence of amino acids of a protein.

For any one codon, there can be only one amino acid that it codes for. Each codon in the genetic code corresponds to a specific amino acid, ensuring that the correct sequence of amino acids is produced during protein synthesis.
One letter accounts for one nitrogen base, which is part of a codon, which codes for one amino acid.
It is a codon.The word was coined in 1962 by Sydney Brenner for a group of three nucleotides (or their bases) in DNA that code for one amino acid. Since then the word has also been extended to apply to messenger RNA.
The actual process is pretty complicated. If you're just looking for a simple overview, the answer is that any given sequence of three bases codes for a specific amino acid. Since there are four (basically...) bases, that means there are 4x4x4 = 64 possible combinations. That's more than the number of biologically important amino acids by quite a bit, so it's actually normal for more than one sequence to code for the same amino acid. Also, certain particular combinations are used for signalling (start here, stop here) rather than for amino acid selection.
The sequence of nitrogenous bases in DNA is important for genetic information and protein synthesis because it determines the specific instructions for making proteins. Each sequence of bases codes for a specific amino acid, which are the building blocks of proteins. The order of these bases in DNA determines the order of amino acids in a protein, ultimately influencing the structure and function of the protein.
