WebIn the first of the two stages of making protein from DNA, a gene on the DNA molecule is transcribed into a complementary mRNA molecule. Stage 1: Initiation. A region at the beginning of the gene called a promoter —a particular sequence of nucleotides—triggers the start of transcription. Stage 2: Elongation. Web19 jun. 2013 · Muscle Protein Synthesis. All the protein needed by muscle is extracted through the intestinal tract into the bloodstream as individual amino acids. Those amino acids will either be used individually or combined to form some kind of peptide chain (multiple amino acids strung together) that has a specific function.

WebThe process of protein synthesis does not occur constantly in the cell, but rather at intervals followed by periods of genetic “silence.” Thus, the process of gene expression is regulated and controlled by the cell. The control of gene expression can occur at several levels in the cell. For example, genes rarely operate during mitosis.

WebGenetic Control of Enzyme Production in Prokaryotes O Genes control protein synthesis.
