Term
Nonoverlapping gentic code
Definition
Refers to the fact that generally each nucleotide is a part of only one codon and codes for only one amino acid.
Term
Triplet codon
Definition
Refers to the fact that three nucleotides encode each amino acid in a protein.
Term
Degenerate code
Definition
Refers to the fact that the genetic code contains more information than is needed to specify all 20 common amino acids.
Term
Synonymous codons
Definition
Different codons that specify the same amino acid.
Term
Codon
Definition
Sequence of three nucleotides that codes for one amino acid in a protein.
Term
Anticodon
Definition
Sequence of three nucleotides in tRNA that pairs with the corresponding codon in mRNA in translation.
Term
Sense codn
Definition
Codon that specifies an amino acid in a protein.
Term
Nonsense codon
Definition
Codon in mRNA that signals the end of translations; also called stop codon or termination codon. There are three codons: UAA, UAG, and UGA.
