There are three codons that do not code for any amino acids: the stop codons. These are TAG, TAA, and TGA (in DNA, not RNA).
Stop codons UAA, UAG and UGA do not code for amino acids
UAA, UAG, and UGA

1. the start codon 2. 150 codons, 1 for each amino acid 3. the stop codon The total number of different codons is 64...if this question is asking about unique codons used the answer will depend on which amino acids are in the peptide.
61 codons specify the amino acids used in proteins and 3 codons (stop codons) signal termination of growth of the polypeptide chain...so 64 total
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.
61. there are 64 total codon arrangements. However three of those (UAA, UAG, UGA) are STOP codons and in turn do not call for the tRNA to bind a protein. Rather, these 3 codons call for termination of translation. The START condon in RNA is UAG, with calls for the amino acid (Met'). It is important to remember that even though there are 61 codons that call for amino acids, only 20 amino acids are available. This means that more than one codon can call for the same amino acid which brings about the REDUNDANT characteristic of codons. However they are NOT AMBIGUOUS, meaning that a codon cannot call for several different amino acids. Serveral codons can call for the same amino acid, but each codon can only call for ONE specific amino acid.
A codon is a 3-nucleotide sequence which codes for an amino acid. This basically means codons help to form polypeptide changes since each one codes for an amino acid. hope that helps :)
There are 64 codons (3-base code) that represent 20 amino acids and 3 stop signals. Click on the related link to see a table of DNA codons and the amino acids for which they code.

One codon is 3 bases long - this codes for one amino acid. Therefore you would need 9 bases (3 codons) to make 3 amino acids.
tRNA. Transport ribonucleic acid, it is a 3 loop structure that brings specific amino acids to the ribosome. Has anticodons specific to the codons.

It is the DNA bases which can trascribe to RNA and then to proteins(polymer of aminoacids)
Transfer RNA comes in sets of three bases. You can arrange four different things into a large number different sets of three. Each combination of bases in Transfer RNA codes for a different amino acid.
each codon have 3 nitrogenous bases . 3 nitrogenous bases = 1 amino acid or say 1 codon =1 amino acid ,so 2 codon = 2 amino acid
The sequence of codons in mRNA, or messenger RNA, is most directly responsible for the sequence of amino acids in a protein. Each codon is comprised of 3 nucleotides.
