Identify the specific mode of inheritance.
1.) Mae is affected with the disease phenylketonuria (PKU). The PKU gene codes for the production of the enzyme that metabolizes phenylalanine. Nonfunctionality of this gene can lead to intellectual disability, seizures, and other serious medical problems.
2.) Duchenne muscular dystrophy results from the mutation of the dystrophin gene. While both sexes carry the mutation, females rarely exhibit signs of the disease.
Explain Loss of p53 function leads to genomic instability?
Talk about the challenges involved in determining the genetic components of polygenic illnesses.
Explain complementation groups and how the biochemical underpinnings of disease are determined using them.
Hereditary illnesses of genomic instability include Werner syndrome, Bloom syndrome, XP, ataxia-telangiectasia, and Fanconi anemia. Which of these ailments has molecular mechanisms behind it? Which kind of genetic instability is connected to which disorder?.
