UAA, UAG, UGA are the 3 stop codons in the genetic code. Stop codons don't code for an amino acid because they cannot be recognized by a tRNA.
The genetic code for proteins is composed of three-letter sequences known as codons. There are a total of 64 possible codons, which correspond to the 20 amino acids used to build proteins, as well as specific start and stop signals.
The genetic code is a set of rules that specify the correspondence between nucleotide triplets (codons) and the amino acids they encode. The start codon is AUG, which codes for the amino acid methionine and also serves as the initiation signal for protein synthesis. There are three stop codons: UAA, UAG, and UGA, which signal the termination of protein synthesis.
Codon combinations can be thought of as one word in the genetic message. Codons are the three-letter sequences of mRNA that correspond to a specific amino acid or a start or stop signal in protein synthesis. Multiple codons are strung together to code for the sequence of amino acids that make up a protein.
There are 64 possible triplets. At least one of the triplets needs to be a stop codon, so theoretically 63 different amino acids can be coded for. In practice, there's some redundancy, and in humans all codons are either stop codons or translate to one of twenty amino acids.

The specific sequences of nucleotides that serve as the stop codons in the genetic code are UAA, UAG, and UGA. The start codon is AUG.
The genetic code for proteins is composed of three-letter sequences known as codons. There are a total of 64 possible codons, which correspond to the 20 amino acids used to build proteins, as well as specific start and stop signals.
The three codons UAA (ochre), UAG (amber), and UGA (opal) that do not code for an amino acid but act as signals for the termination of protein synthesis.
The codons that signal the termination of protein synthesis are known as stop codons. In the genetic code, there are three stop codons: UAG, UAA, and UGA. When a ribosome encounters one of these codons during translation, it signals the end of protein synthesis and the release of the completed protein.
Codons consist of three bases. Each codon corresponds to a specific amino acid or a stop signal in the genetic code.

The ratio of codons to amino acids is typically 3:1, as each codon consists of three nucleotides that correspond to one amino acid in the genetic code. However, there are 64 possible codons (including stop codons) but only 20 standard amino acids, which means some amino acids are encoded by multiple codons. This redundancy in the genetic code helps to minimize the effects of mutations.

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).
Of the 64 codons, the three that do not code for amino acids are stop codons.The stop codons are:TAG in DNA (UAG in mRNA)TAA (UAA)TGA (UGA)They signify the end of the gene, i.e. the end of the segment to be transcribed and translated.
