A codon is a sequence of three adjacent nucleotides in mRNA (messenger RNA) that corresponds to a specific amino acid or a stop signal during protein synthesis, and serves as the genetic code's basic unit, specifying the sequence of amino acids in a protein.
The genetic code links groups of nucleotides in an mRNA to amino acids in a protein. Start codons, stop codons, reading frame.
3 dni temu · A codon is a DNA or RNA sequence of three nucleotides (a trinucleotide) that forms a unit of genomic information encoding a particular amino acid or signaling the termination of protein synthesis (stop signals). There are 64 different codons: 61 specify amino acids and 3 are used as stop signals.
When the correct tRNA finds the mRNA, its amino acid is added to the growing protein chain. Enzymes catalyze the bonding of amino acids together as tRNA anticodons bind to the correct mRNA codon. Study with Quizlet and memorise flashcards containing terms like Codon, mRNA, Reading frame and others.
28 lip 2023 · 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. There are 20 common amino acids in proteins.
