Term
|
Definition
| in DNA, a three-nucleotide sequence that encodes an amino acid or signifies a start signal or a stop signal |
|
|
Term
|
Definition
| the rule that describes how a sequence of nucleotides, read in groups of three consecutive nucleotides(triplets) that correspond to specific amino acids, specifies the amino acid sequence of a protein |

Term
|
Definition
| the formation of proteins by using information contianed in DNA and carried by mRNA |
|
|
Term
|
Definition
| a specific sequence of bases in mRNA to which a molecule of tRNA binds in the first step of protein synthesis |
|
|
Term
|
Definition
| in an mRNA molecule, a sequence of three nucleotides (UUA,UAG, and UGA)that does not encode an amino acid and therefore stops protein synthesis |
|
|
Term
|
Definition
| the portion of protein synthesis that takes place at ribosomes and that uses the codons in mRNA molecules to specify the sequence of amino acids in polypeptide chains |
