REGULATION OF GENE EXPRESSION Gene Genetic regulatory protelns bind to the DNA and control the rate of transcription. Transcription In attenuation, transcription terminates soon after It has begun due to the formation of a transcriptional terminator. MRNA Translation Translational repressor proteins can bind to the MRNA and prevent translation from starting. Riboswitches can produco an mRNA conformation that provonts translation from starting. Antisense RNA can bind to the MRNA and prevent translation from starting. Protein Posttranslation In feedback Inhibition, the product of a metabolic pathway Inhibits the first enzyme in the pathway. Covalent modifications to the structure of a protoin can altor Its function. Functional protein

Mitochondrial Mutations

A mitochondrion is a cellular organelle that serves as the site for cellular respiration and energy production (ATP or Adenosine Triphosphate). It is a double-membrane-bound organelle and is only present in eukaryotic cells.
