Difference Between Start Codon and Stop Codon
In conclusion, start codons, such as AUG, initiate protein synthesis by indicating the beginning of translation, guiding the ribosome to assemble amino acids. In contrast, stop codons (UAA, UAG, UGA) serve as termination signals, instructing the ribosome to terminate protein synthesis and release the newly formed polypeptide. The distinction lies in their roles: start codons initiate the process, while stop codons bring it to a timely and precise conclusion, collectively ensuring the accurate translation of genetic information into functional proteins.
Difference between Start Codon and Stop Codon
Start and stop codons are two punctuation marks of the genetic code that signal the beginning and end of protein synthesis. The main difference between the start and stop codon is that the start codon marks the site at which translation into protein sequence begins whereas the stop codon marks the site at which translation ends. The most common start codon is AUG which codes for methionine while there are three stop codons UAG, UAA, and UGA, and they do not code for an amino acid.
