Chromosomes are tightly wound strands of DNA.
Answer: A short incubation time runs the risk of a false negative on the VP test, since not enough time may have elapsed to produce an adequate amount of acetoin to give a positive result. The pH change associated with mixed acid fermentation occurs fairly quickly and is less likely to be affected by shorter incubation.
b) The VP test would benefit most from a longer incubation time because it takes a while for the 2,3-butanodiol to be produced.
Explanation:
Explanation:
Gene therapy is the therapeutic delivery of the nucleic acid into the patients cells in the form of drug to treat disease. It is a complex treatment involves more potential for the treatment of the monogenic diseases and is also associated with a lot of significant risks . The children who were suffering from Wiskott- Aldrich syndrome which is a rare disease and were treated as the part of the clinical gene therapy trial which was carried out in the Germany. After treatment, health of children improved significantly. Then after one to three years following the gene therapy, seven out of ten children developed the cancer in the blood .
Public response towards gene therapy and acceptability of changing the genes varied a good deal from one scenario to the another. Many more techniques needed to be developed and more information of the diseases that need to be understood before the gene therapy which involve changes on the genetic setup of the body , it raises many unique ethical concerns. For decades researches are done to bring the gene therapy to clinic , still very less patients are given any effective gene therapy treatments . Even though gene therapy has been slow to reach patients, it's future is encouraging.
