4. Huntington's Disease - This is an autosomal dominant disorder which means that only one copy of defective gene may result in the disorder. All others are recessive disorders.

Sickle-cell Anemia Study Sickle-cell anemia or Sickle-cell disease, is a hereditary disorder. characterized by aryabnormality in the oxygen-carrying hemoglobin molecule in erythrocytes. Sickle-cell conditions have an autosomal recessive pattern of inheritance from parents. The sickle cell defect is a mutation of a single nucleotide of the hemoglobin B gene, which results in glutamic acid being substituted by a different amino acid at position 6. Hemoglobin with this mutation is referred to as Hbs, as opposed to the normal hemoglobin HbA....
Question 2 Imagine you are a scientist who intends to cure sickle cell disease. Which approach would be best suited to this goal? a. Dietary supplements to make up for an enzyme deficiency b. Modification of ribosomes to enhance translation c. Exposure to X-rays to induce a new mutation d. Dietary supplements to make up for an amino acid deficiency e. Editing the gene for a polypeptide component of hemoglobin Question 7 Stop codons terminate translation by a. increasing peptidyl...
3. Cystic fibrosis (CF) is an autosomal recessive disorder (cc) and is one of the most common life-shortening genetic diseases. In the United States, 1 in 4,000 children are born with CF. Symptoms of cystic fibrous include the production of salty sweat and thickened mucus in the lining of the lungs and air passages. The thickened mucus obstructs airways and promotes the growth of disease-causing bacteria in the lungs. Most individuals with cystic fibrous die in their 20s and 30s...

6. Cystic fibrosis is autosomal recessive (r). The genotype of a CF patient should be Huntington's disease is a disorder. The possible genotypes of a Huntington patient are Hemophilia is a disorder. Both parents are normal, their son has hemophilia. What is the mother's genotype? What is the father's genotype? What is the son's genotype? If they have a daughter, what would her phenotype be? Her possible genotype should be...
2 points O In individuals with Sickle Cell Disease, only the adult form of hemoglobin carries a mutation in the myoglobin subunit. A potential therapeutic approach is to reactivate the expression of fetal myoglobin, which is normal and would reverse the disease. Which of the following steps is most likely to succeed in promoting transcription of fetal myoglobin in adult cells? Altering the expression of transcription factors to redirect the enhanceosome to the fetal gene promoter Removing the adult myoglobin...
