Document Summary

Transcription a process catalyzed by the enzyme rna polymerase that uses 1 strand of dna as the template to synthesize a complementary rna sequence (sometimes called the primary transcript) Genetic code a set of rules that specify the correspondence between nucleotide triplets (codons) in dna or rna and amino acids in proteins. Template strand a specific sequence of nucleotides in dna that acts as a template to direct the synthesis of a new strand of complementary dna (dna that is copied during the synthesis of mrna) Coding strand - the dna strand that has the same base sequence as the rna transcript produced - although t u. Coding strand contains codons, non-coding strand contains anticodons. Sigma factor - a bacterial transcription initiation factor that enables specific for the binding of rna polymerase to gene promoters; a protein needed only initiation of rna synthesis. Promoter a nucleotide sequence in dna to which rna polymerase binds in order to begin transcription.
