Cystic fibrosis

*************************************************** Q: 1. Look at the male and female dragons on the left. Notice that they both have horns. Can two dragons with horns have a baby dragon with no horns? A: Yes Q: 2. Why do you think it can be done? A: If each parent has Hh to make up their horns, as long as the gametes that are used in fertilization are h, then the baby will have horns. Q: 3. OK, let's make sure you remember the rule for horns. Here's a little quiz: Which of these genotypes do…

Question 1A: Compare and contrast the general structure of a virus and a bacterium. Bacteria and viruses both do not contain a DNA enclosing nucleus; however, these organisms differ greatly in the complexity of their structures. Generally a bacterium is encompassed within a semi-rigid cell wall made of peptidoglycan, which provides structural support. It is classified as gram positive if its cell wall is thick and stains purple when tested for identification. If its cell wall is thin and stains…

Parents should not be allowed to play God or Nature to choose a child's gender. Women are choosing the gender of their children for reasons such as genetic diseases, family balancing, or just wanting the choice. According to Sureau , " In the prevention of X-linked diseases, e.g. Duchenne myopathy, haemophilia, there are the following choices: (i) pre-natal diagnosis, followed by medical termination if the fetus is male or termination which is restricted to affected male fetuses; (ii)…

The ethics of gene manipulation proposes a rather complex debate because of opposing religious/individual takes on this issue. My position on this issue is “in-between” because this could be a fantastic advancement at rescuing a family from a harmful genetic disease passing on and advances in genetic engineering have and still could enable an abundance of people with infertility problems to start a family. Although, the negative impacts of gene manipulation remain vital, it violates a child’s…

developed first by the parent company of the drug, Vertex. Together though these groups form an extremely expensive medicine for an extremely dangerous disease. Treatment with Ivacaftor had significant and sustained in their lung function in cystic fibrosis [3.2]. The sky high price of brand name…

Viruses are found wherever there is life and have probably existed since living cells evolved, but the origin of viruses is unclear because they do not form fossils. Instead, researchers have resorted to using molecular techniques to compare DNA of viruses to other organisms. Studies at the molecular level have revealed relationships between viruses infecting organisms from each of the three domains of life and viral proteins that pre-date the divergence of life and thus the last universal…

possible to suffer from Cystic Fibrosis, especially if both of the families of the parents of the offspring have anyone in the lineage with Cystic Fibrosis. Cystic Fibrosis causes excessive mucus that is unusually thick and sticky. The mucus that lines the lungs also is affected, and the thick mucus can lead to lung infections. This mucus also may cause the pancreas to be obstructed, causing it to no longer be able to release enzymes for digestion. Symptoms and signs of cystic fibrosis are or…

Explain the potential effects of five different life factors on the development of an individual There are five different types of factors that can influence the development an individual for example, lifestyle influences, socio-economic influences, genetic influences, biological influences and environmental influences. Lifestyle In relation to Stephen, a lifestyle factor could be alcohol. If Stephen had taken alcohol these would have been the effects that would or could have happened. Many…

me know that I am free from STDs, and if I was a Cystic Fibrosis carrier. I was devastated when she told me I was a carrier of Cystic Fibrosis which meant that if my husband had it our baby will have it too. Risk Factor/Birth Defect: This month I did not smoke nor think about doing so. I have chosen to completely quit for the sake of my baby’s health. The doctor informed me that my baby has a really high chance of being born with cystic fibrosis if my husband is a carrier as well. We will…

we are capable of using this practise to correct gene defects in unborn children, meaning that in the future we may be able to prevent genetic disorders such as Down Syndrome and Cystic Fibrosis. Whether this is ethical, however, is still in debate. There are many hereditary diseases, such as Haemophilia A, Cystic Fibrosis and Down Syndrome that are the result of genetic disorders and mutations. Although these disorders are extremely rare, usually affecting one person in every several thousands…
