A stop codon is a nucleotide sequence in mRNA that signals the end of the protein synthesis process. It is also known as a termination codon, since it marks the point at which the ribosome releases the completed protein chain. There are three different stop codons: UAA, UAG, and UGA. These codons do not code for an amino acid, but instead signal the end of protein synthesis.
A stop codon, also known as a termination codon or nonsense codon, is a specific sequence of three nucleotides (A, U, G, or C) in RNA that signals the end of protein synthesis. There are three stop codons: UAA, UAG, and UGA. When the ribosome encounters a stop codon during the process of translation, it recognizes it as a signal to stop protein synthesis and releases the completed protein chain. Stop codons do not code for any amino acid and do not have corresponding tRNA molecules. Instead, they act as termination signals in the genetic code.
