Yes, each amino acid has several codons that correspond to it. Please see the related link for a chart which shows this.
For example, UUU and UUC both code for Phenylalanine.
However, if you are asking if a codon can code for more than one amino acid, the answer is no (but there are exceptions). This means that UUU codes for Phenylalanine - not for any other amino acids. Codons are made in sets of three bases to match the anticodons in corresponding sets of three bases.

Where does the amino acid table use the code from?
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.
Name a codon for the amino acid arginine?
arginine - is an amino acid that plays a role in cell division, healing of wounds, removing ammonia from the body, improving immunity to illness, and hormone secretion. Arginine is used by the body to make nitric oxide, condon -three bases in a DNA or RNA sequence which specify a single amino acid.
How many nucleotides make an amino acid?
3 are needed. As there are 20 amino acids used in proteins, each amino acid would have to be encoded by a minimum of three nucleotides. For example, a code of two consecutive nucleotides could specify a maximum of 16 (42) different amino acids, excluding stop and start signals. A code of three consecutive nucleotides has 64(43) different members and thus can easily accommodate the 20 amino acids plus a signal to stop protein synthesis.
Why is it possible for an amino acid to be specified by more then one kind of codon?
Im pretty sure its "Some codons have the same sequence of nucleotides" It keeps repeating nucleotides over and over in the paragraph in my textbook. Mine just goes "Because there are four different bases, there are 64 possible three-base codons. As you can see [it shows genetic code chart], some amino acids can be specified by more than one codon. So I kind of think it has to do with there being so many possibilites.
Explain the process of translation and tRNA anticodons?
In short, translation is the process of ribosomes reading mRNA and using tRNA to gather the amino acids specified by the mRNA. The tRNA anticodons are complementary to the codons (three nucleotide sequence that represents an amino acid) on mRNA and allow them to be identified by the ribosome. In detail, translation is the second process of making a protein or polypeptide, the first being transcription. During translation, the mRNA leaves the nucleus and moves to the ribosome, usually located on the Rough ER (endoplasmic reticulum) or in the cytoplasm of the cell. The ribosome consists of two subunits, a large and small one. Initiation factors take the mRNA to the small ribosomal subunit, where other initiation factors move the tRNA to the first codon (three nucleotides sequence that represents a particular amino acid.) Then, the large ribosomal subunit attaches to the small subunit, encasing the mRNA and tRNA. The ribosome contains three distinct areas that the tRNA can occupy in the ribosome: the A site, where tRNA enters and receives the existing amino acid chain, the P site, where it comes in contact with the codons on the mRNA, and the E site, where the tRNA prepares to leave the ribosome. The first tRNA enters the P site and always carries N-formylmethionine (fMet), and all subsequent tRNAs enter the A site, then move to the P site then E site. Since tRNA is reusable and can only carry a particular amino acid, its possesses anticodons that represent the amino acid it carries. The first codon on mRNA is always a 'start' codon AUG (amino acid Methionine.) The ribosome moves down the mRNA and 'reads' each mRNA codon and finds the tRNA with the complementary anticodon (for example, if a codon on mRNA was GGG (Glycine), the complementary tRNA would have an anticodon of CCC and would be carrying the amino acid Glycine.) At the end of the mRNA, a stop signal is read by the ribosome and a release enters the A site instead of tRNA, prompting the ribosome to disassemble and be made available for more mRNA. The stop codons (also known as nonsense codons) are UAA, UAG, and UGA; they do not translate into any amino acid.
All amino acids are specified by only one codon?
No. Some are specified by only one codon eg. methionine and tryptophan. But some have more than one codon eg. threonine.
The genetic code is degenerate?
Each amino acid can be specified by more than one codon.
Is it impossible for an amino acid to be specified by more than one codon?
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.
How many amino acids does each condon code for?
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".
There can be more than one for the same amino acid?
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.
Is it possible for an amini acid to be specified by more than one codon?
Yes. There are 64 different codons and only 20 amino acids.
How many amino acids make a codon?
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.
What are the amino acids on the codon table?
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.
What does each single codon stand for or code for protein production to stop?
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.
Why can an amino acis be specified by more than one kind of codon?
see Related Answers.
What about the degenracy of genetic code?
Type your answer here... the degenracy of code means there are more than one codons for one amino acid.The opposite of it ie.non-degeneracy of codon means ther is only one codon for one amino acid.
How is a genetic code is redundant?
There are 64 codons, that code for only 20 amino acids. This make the genetic code redundant - because different codons can code for the same amino acid.This provides some protection against mistakes - because a replacement of a single base may end up coding for the same amino acid - causing no change to the final protein product.
