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.

Explain why the genetic code is redundant
Hydrogen bonds are important in DNA replication and transcription. They are relatively weak chemical bonds. Why is this a desirable feature for DNA? Describe the effect (s) of changing (mutating) the promoter on the transcription of the DNA strand/gene the promoter controls. What happens to protein synthesis if a nonsense codon is inserted into the gene? Explain why a point mutation does not necessarily change the original amino acid sequence. (Explain silent mutations) Choose any pentapeptide composed of five different amino acids. List the amino acids. Present one messenger RNA codon for each amino acids and the sequence of nucleotides on the DNA that originally coded for your pentapeptide.

Leber's Hereditary Optic Neuropathy (LHON) is a disease that involves degeneration of neural cells in the retina and results in loss of central vision. The disease is caused by mutations in any one of three genes in the mitochondrial genome that encode proteins involved in oxidative phosphorylation. In a genetic counseling clinic, a woman and her husband seek advice on the potential that any of their children would be afflicted with LHON. The husband's mother and father, both exhibit symptoms of the disease, but the woman does not. What is a reasonable advising statement to make? There is not enough information to advise this couple. a. The couple should be advised that all of their children are likely to display symptoms of LHON. b. The couple should be advised that all their female children will display symptoms of LHON, but male children will be unaffected. C. The couple should be advised that all their male children will display symptoms of LHON, but female children will be…

Cystic fibrosis is genetic disease caused by mutations in the CFTR gene. The consequence of this is production of an abnormal transmembrane protein that is responsible for producing sweat, mucus, and digestive fluids. Please mention the process involved in protein production, whether or not those process(s) have occurred, and their end products.
In the eukaryotic cell, the members of the endomembrane system work together to synthesize protein products used for excretion out of the cell (e.g. insulin, milk etc.) and for use within the cell (e.g. lysosomes etc.).
