To explain:
The requirement to use genetic testing to check the disease in an embryo before the technique of the in-vitro fertilization, analysis of the embryo for testing to check for traits unrelated to the diseases. The analysis of the feasibility of performing the genetic tests and to draw a line of conclusion for the genetic tests which are acceptable and which are not.
Introduction:
The genetic testing by the procedure of amniocentesis is done to analyze the diseases in the embryo. In this technique, a small amount of amniotic fluid is extracted from the embryo sac layer inside the uterus of the mother and diagnosed for the pre-natal diseases. The technique of in-vitro fertilization is used for fertilizing the egg with a sperm in a test-tube and implanting the egg in the uterus of the mother at the eight-celled stage.

- magine that you are conducting research on fruit type and seed dispersal. You submitted a paper to a peer-reviewed journal that addresses the factors that impact fruit type and seed dispersal mechanisms in plants of Central America. The editor of the journal communicates that your paper may be published if you make ‘minor revisions’ to the document. Describe two characteristics that you would expect in seeds that are dispersed by the wind. Contrast this with what you would expect for seeds that are gathered, buried or eaten by animals, and explain why they are different. (Editor’s note: Providing this information in your discussion will help readers to consider the significance of the research).arrow_forwardWhat is the difference between Uniporters, Symporters and Antiporters?
