What is one goal of gene therapy?
The goal of gene therapy is to cure a genetic disorder. Lets a gene is impaired by mutation and causing a disease. We can correct the gene by injecting DNA to the cells that have impaired gene. By this we can find out a permanent cure of that particular disease condition if it works properly.
Can celiac disease develop when a person is in their teens?
Yes, Celiac Disease can develop at anytime. For a person to develop Celiac Disease, one must carry the gene. The gene can remain "off" or it can turn "on". You can have the gene but never experience any celiac disease symptoms. Something has to trigger the gene for a person to start developing problems. My mom didn't have symptoms until she was in her 30's. Before that, she never had any problems eating grains.
What is a likelihood that a person who has two parents with the disease will be a carrier of the defective gene?
100%
What carriers that are related to biology?
carriers are a parent carrying the particular recessive gene for a disease but is not affected by that disease. However, its offspring will have that gene as dominant increasing its chances of being affected by that disease if the parent mates with another parent of the opposite gender who is also a carrier.
What is hidden in the heterozyotes?
Heterozygotes have two different alleles for a particular gene, where one allele is dominant and the other is recessive. The recessive allele is "hidden" in heterozygotes because it is not expressed phenotypically but can be passed on to offspring.
Sickle-cell anemia is a disease passed by autosomal recessive inheritance. What is the likelihood that a person who has two parents with the disease will be a carrier of the defective gene?
If both parents have sickle-cell anemia, their child will inherit one copy of the defective gene from each parent, making them a carrier. Thus, the likelihood that a person who has two parents with the disease will be a carrier of the defective gene is 100%.
. Is a person who is homozygous recessive for a recessive genetic disease a carrier?
No, because he or she cannot pass the gene on to his or her offspring (because he or she does not have a copy of the gene).
What Does a particular trait result from the expression of a single gene?
Huntington's disease is a perfect example of a single gene trait. A mutation in this allele causes Huntington's disease in later life. A dominant trait. Widows peak us another. Any gene that controls the total expression of a trait is an allele defined as a single gene trait.
A person who does not show a genetic disease such as Tay Sachs or Cystic Fibrosis but can pass the gene on to the next generation is called?
A carrier. This is usually a disease that requires two parts of a gene. The faulty gene is the recessive gene, and the healthy gene is the dominant gene. If two people with one dominant and one recessive gene each have a child they have a 25% chance of producing a child with two dominant genes, thereby resulting in that child having the disease.
What is gene therapy Explain?
If a person is lacking a gene that causes a disorder, for example Diabetes, and a gene can be inserted into cells that require the gene, this would be gene therapy. Parkinson's disease and X-linked SCID are two that are be researched.
Explain what human gene therapy is?
Human gene therapy is a type of treatment that involves introducing genetic material into a person's cells to treat or prevent disease. This can involve inserting a healthy gene to replace a faulty one, repairing a mutated gene, or introducing a new gene to help the body fight disease. Gene therapy has the potential to treat genetic disorders, cancer, and other diseases by addressing the underlying genetic causes.
Can a person be a carrier for a genetic disease if neither or only one of their parents are carriers?
Yes, it is possible for a person to be a carrier for a genetic disease even if neither of their parents are carriers. This can occur if the person has a new mutation in the gene associated with the disease. Carriers have one copy of the mutated gene, which they can pass on to their children.
