How many stop codons exist in the standard genetic code?

Explanation:
Stop codons act as termination signals during translation. In the standard genetic code, there are three stop codons: UAA, UAG, and UGA. They do not code for any amino acid; instead, release factors recognize them and trigger the ribosome to release the finished protein. Of the 64 possible codons, 61 specify amino acids and 3 signal termination, so the standard code uses three stop codons. In DNA terms, these are TAA, TAG, and TGA. Note that some organelles or organisms use variant codes, but in the standard code there are three stop codons.
