The genetic code links groups of nucleotides in an mRNA to amino acids in a protein. Start codons, stop codons, reading frame.
A codon is a sequence of three DNA or RNA nucleotides that corresponds with a specific amino acid or stop signal during protein synthesis. DNA and RNA molecules are written in a language...
Describe a codon and how they are used in translation. Given the different numbers of “letters” in the mRNA and protein “alphabets,” scientists theorized that combinations of nucleotides corresponded to single amino acids.
The bases are adenine (A), cytosine (C), guanine (G), and thymine (T) (or uracil, U, in RNA). The four bases make up the “letters” of the genetic code. The letters are combined in groups of three to form code “words,” called codons. Each codon stands for (encodes) one amino acid unless it codes for a start or stop signal.
5 lis 2019 · The code is read in triplet sets of nucleotide bases, called codons, that designate specific amino acids. For example, the codon UAC (uracil, adenine, and cytosine) specifies the amino acid tyrosine. Some codons represent start (AUG) and stop (UAG) signals for RNA transcription and protein production.
