Each codon codes for only one amino acid, or a codon is a start or stop codon, but no codon codes for more than one amino acid.
yes, but there are amino acids can be represented by many codons.
No. On the contrary, most amino acids are specified by more than one codon. Click on the related link to see a table of amino acids and their codons from the Algorithmic Arts website.
A codon is a sequence of three nucleotides in DNA or RNA that codes for a specific amino acid. A sense codon is a codon that specifies one of the 20 standard amino acids in protein synthesis.
No they are not. For a codon, there are 4^3 = 64 codon combinations, but only 20 [common] amino acids. The 4 represents the 4 nitrogenous bases, and the ^3 represents the arrangement into a codon (3 bp). An example of an amino acid that is specified by more than one amino acid is Alanine, which is specified by any of the following combinations: GUU, GUC, GUA, GUG. Because most amino acids have more than one codon, the genetic code is called "degenerate".
Several amino acids are not coded for in biology. 20 are. The two standard amino acids are selenocysteine and pyrrolysine. Then there are the numerous non-standard amino acids, which include hydroxyproline and selenomethionine.
A codon contains three amino acids. Each codon in mRNA corresponds to a specific amino acid in a protein sequence.

There can only be one amino acid for every codon. Tryptophan and Methionine are the types of amino acids that correspond to codon.
Codons are three bases on mRNA which go to the ribosome which translates into amino acids. The amino acids are attached to tRNA which has the anticodon on it which will bind to the codon on the mRNA. This is how the ribosome picks out the correct amino acid. the tRNA with the anti codon just binds to the codon and the amino acids start binding together via peptide bonds.
One codon specifies a specific amino acid. However, more than one codon can code for the same amino acid. For example, the codon GUU codes for the specific amino acid valine; and the codons GUC, GUA, and GUG also code for valine.

Methionine, made from the codon AUG.
No. Amino acids are not always represented by only one codon. Several may code for one amino acid.
No. Some are specified by only one codon eg. methionine and tryptophan. But some have more than one codon eg. threonine.
