Document Summary
Chapter 17 (gene expression: from gene to protein) Gene expression process by which dna directs the synthesis of proteins. 17. 1 genes specify proteins via transcription and translation. Transcription synthesis of rna using information in dna. Dna serves as a template for creating a rna strand. Mrna carries genetic information from dna to protein synthesizing region. Translation synthesis of polypeptide using information in rna: occurs at ribosome, nucleotide sequence on mrna translated to amino acid sequence of polypeptide.

Because of this, translation can begin while transcription occurs, whereas in eukaryotes, the rna has to be transported outside the nucleus into the ribosome first. Primary transcript the rna made as a result of transcription. Codon three bases that code for an amino acid on nontemplate strand: why nontemplate strand is referred to as coding strand. Template strand the one dna strand that is transcribed upon.
