There can be more than one codon for the same amino acid. The codon is the three letter code that is found in the mRNA.
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.
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".
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.
Yes it is. There are more triplet codons than there are [biologically active] amino acids that need to be represented in the Cell, so that there is some duplication of codon/amino acid 'alignment'. This occurs only in the third base position of the triplet codon - the 'wobble base' position - so if a mutation occurred in the wobble (third) position and the codon was one of the few that was not alone in its amino acid specificity this mutation would go unnoticed.

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.
No. Some are specified by only one codon eg. methionine and tryptophan. But some have more than one codon eg. threonine.

Each messenger-Rna codon stands for one [unique] Amino Acid. ONE mRna - called f-Met Rna - IS [represents] The Start Codon. There are also more than one Stop Codons.
Yes. There are 64 different codons and only 20 amino acids.

The three base pairs called codons.
Yes it is. There are more triplet codons than there are [biologically active] amino acids that need to be represented in the Cell, so that there is some duplication of codon/amino acid 'alignment'.

I'm unsure what your question means, but if I interpreted correctly, the codes on the amino acid table are codons. So they are the codes that would be found on the mRNA. If you are looking up an amino acid on the table, just use the one it says under the codon you want to translate. For example, if the codon is AUG, the amino acid is just methionine. No need to do anything more.
