1. Codons are sequences of three nucleotides that correspond to a specific amino acid or stop signal in protein synthesis.
2. The process of translation involves the conversion of information from mRNA into a sequence of amino acids in a protein.
3. Each codon on the mRNA strand is recognized by a specific tRNA molecule, which carries the corresponding amino acid.
4. The genetic code, which determines which codons correspond to which amino acids, is nearly universal among all organisms.
5. There are 64 possible codons, but only 20 amino acids, so some amino acids are coded by more than one codon.
6. The start codon (AUG) not only signals the start of translation, but also codes for the amino acid methionine.
7. There are three stop codons (UAA, UAG, UGA) that do not code for any amino acid and instead signal the end of protein synthesis.
