How do you think genomics and genetic engineering will contribute to the development of more productive food crops and what ecological implications should be considered? Be sure to include examples of existing and future GMOs that are contributing to the debate. What are the main criticisms of the Green revolution, and how can we mitigate some of the negative aspects? Cite your work
Answer:
The importance of optimal nutrition for human health and development is well recognised. Adverse environmental conditions, such as drought, flooding, extreme heat and so on, affect crop yields more than pests and diseases. Thus, a major goal of plant scientists is to find ways to maintain high productivity under stress as well as developing crops with enhanced nutritional value. Genetically-modified (GM) crops can prove to be powerful complements to those produced by conventional methods for meeting the worldwide demand for quality foods. Crops developed by genetic engineering can not only be used to enhance yields and nutritional quality but also for increased tolerance to various biotic and abiotic stresses. Although there have been some expressions of concern about biosafety and health hazards associated with GM crops, there is no reason to hesitate in consuming genetically-engineered food crops that have been thoughtfully developed and carefully tested. Integration of modern biotechnology, with conventional agricultural practices in a sustainable manner, can fulfil the goal of attaining food security for present as well as future generations.

A newly transplanted organ is rejected by the immune system of the host. Which protein is responsible for the rejection
Answer:
Histocompatibility antigens are encoded on more than 40 loci, but the loci responsible for the most vigorous allograft rejection reactions are on the major histocompatibility complex (MHC).
Explanation:
Transplantation involves transferring from one site to another of cells, tissues or organs, often among people. An organ transplant (eg, kidney, liver, cardiac, lung, or pancreas) from a donor may rectify organ malfunction.
The immune system remains as a standard medical treatment the greatest barrier to transplantation. An effective and intricate mechanism has been evolved in the immune system to fight off invading invaders. These systems also contribute to the refusal of the transplanted bodies that are recognized by the immune system of the receiver as foreign.
does the presence of introns exons in eukaroytic cells provide more potentia diversity in gene products than is possible in porkatroi cells
Answer: Yes. Splicing can be done in different ways to yield different mRNAs wich will create different proteins. Prokaryotes are not able to do this.
Explanation:
DNA (deoxyribonucleic acid) is a molecule that contains the genetic information for synthesizing amino acids that form proteins. To do this, DNA must first be transcribed into RNA (ribonucleic acid) and this is the molecule used for protein synthesis (translation). The newly transcribed RNA (called primary messenger RNA) from DNA results in a very long molecule and also has regions that do not code for anything, called introns, which are removed by a process called splicing. Exons are segments in the RNA that do code for amino acids and remain in the mature mRNA after splicing.
Splicing is a process by which introns are cleaved from the primary messenger RNA and exons are joined to generate mature messenger RNA. In addition, alternative splicing occurs which allows different mRNA isoforms and thus different proteins to be obtained from a primary mRNA transcript. This is because the exons will be joined or spliced in different ways, giving rise to different mature messenger RNA sequences. This process occurs mainly in eukaryotes, although it can also be observed in viruses. But it does not take place in Prokaryotes (Bacteria).
In summary, exons/introns can be spliced together in different ways to yield different mRNAs sequences. Each different mRNA sequence will code for a different protein.

According to the theory of plate tectonics what drives the motion of the contenients
Answer:
The theory of plate tectonics is what brings together continental drift and seafloor spreading. Plates are made of lithosphere topped with oceanic and/or continental crust. The plates are moved around on Earth's surface by seafloor spreading. Convection in the mantle drives seafloor spreading. Oceanic crust is created at mid-ocean ridges. The crust moves outward from the ridge over time. The crust may eventually sink into the mantle and be destroyed. If a continent sits on a plate with a mid-ocean ridge, the continent will be pushed along.

The solutions in the two arms of a U-tube are separated by a membrane that is permeable to water and glucose but not to sucrose. Side A is filled with a solution of 4M sucrose and 2M glucose. Side B is filled with 2M sucrose and 3M glucose. Initially, the solution in side A, with respect to side B is______________.
Answer:
hypertonic
Explanation:
The solution in side A is hypertonic with respect to side B.
A hypertonic solution is a solution with a higher concentration of solutes in comparison with a neighbouring solution separated by a selectively permeable membrane.
In terms of both sucrose and glucose concentrations, the solution in side A is higher than the solution in side B of the U-tube. Hence, side A is hypertonic to side B.
A hypertonic solution is as opposed to a hypotonic solution with the latter having a lower concentration of solutes as compared to a neighbouring solution. Isotonic solutions have equal solute concentrations with their neighbouring solutions.
