WebReading: Codons Given the different numbers of "letters" in the mRNA and protein "alphabets," scientists theorized that combinations of nucleotides corresponded to single amino acids. Nucleotide doublets would not be sufficient to specify every amino acid because there are only 16 possible two-nucleotide combinations (42). WebCells decode mRNAs by reading their nucleotides in groups of three, called codons. Each codon specifies a particular amino acid, or, in some cases, provides a "stop" signal that …

The code has several key features: All protein-coding regions begin with the "start" codon, ATG. There are three … WebThe end of a sequence is specified by one of three stop codons: UAA, UAG, or UGA. A consequence of this rule is that the genetic code can be read in three different reading frames depending on which base one begins with.
