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.
There are twenty amino acids in proteins, three bases in a codon and three bases in an anti-codon newly known as an anti-sense codon. If the codons make up mRNA , then the anti-sense codons are found in the transfer RNAs. A triplet codon corresponds to an amino acid. Adenine pairs with Uracil, and Guanine Pairs with Cytosine. Let's say we had a mRNA strand like: AUACGUACGUACGUCACGUGAUGCUACACCUGACAUCCGAUCAUGAGUCGAUCAUGAUGA (oops, there's no more) The first codon is AUA. The anti-codon UAU, would attach to it. AUA corresponds to the amino acid Tyrosine. Then the next anti-codon GCA would attach to the second codon CGU. Arginine corresponds to the codon CGU. Tyrosine would join together with Arginine. The bond of the Tyrosine and its tRNA breaks. This is all done by a ribosome. The process continues until the chain is complete.
The start codon. The codon AUG is generally referred as the start codon because the translation of mRNA begins on AUG.
The start codon is AUG, or Methionine(Met)
the three nucleotides on a mRNA that codes for a amino acid is called a codon
stop codon on mRNA
A nonsense codon, also known as a stop codon, is a three-nucleotide sequence in mRNA that signals the termination of translation. When a ribosome encounters a stop codon, protein synthesis stops, and the incomplete polypeptide chain is released. There are three stop codons: UAG, UAA, and UGA.
In a sense. It regulates the length and the sequence of a polypeptide chain by terminating it's synthesis.

The codon for trytophan is UGG.
anti-codon.
A complimentary codon is one that pairs with another codon according to the base pairing rule. For example, the DNA codon ATG is complimentary to the mRNA codon UAC.
The codon typically used as the start codon in protein synthesis is AUG.
The start codon. The codon AUG is generally referred as the start codon because the translation of mRNA begins on AUG.
Usual start codon is AUG
A codon is a unit of genetic code
The start codon is AUG, or Methionine(Met)
