What is Genetic code?
The universal genetic code is made up of triplet bases or several codons. The standard code has evolved over time to reduce coding errors. There are total 64 codons in the genetic code created from the permutation and combination of the 4 bases in nucleic acids. The genetic code is degenerate that is more than one codon can code for a single amino acid. As a result, out of the 64 codons, 61 codons code for the 20 amino acids. There are two punctuation marks in the genetic code known as the Start and Stop codons which mark the end of protein synthesis in all organisms.
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.
