Chapter 17: Gene expression: from gene to protein
Changes in a nucleotide sequence, if present in a protein-coding region, can change the amino acid sequence of the polypeptide. In other cases, mutations can alter levels of gene expression, or simply be silent.
In order for DNA to direct cellular processes, information must be transcribed (DNA->RNA) and, in many cases, translated
(RNA->Protein). The products of transcription and translation play an important role in determining metabolism, i.e., cellular activities and phenotypes.
Biotechnology makes it possible to directly engineer heritable changes in cells to yield novel protein products.
