Advances in biotechnology have given us genetically modified tomatoes that can survive shipping and arrive at the grocery store with few visible flaws. however, many of these modified tomatoes lose some flavor. what does this example suggest about the issues surrounding food-related genetic modifications? gaining some desired qualities may result in loss of others. genetic modifications are too costly and risky for business to pursue. genetic alteration may affect the plant's long-term ability to survive. people care more about the appearance of food than taste.

What are some things that limit population growth?

What effect does plate tectonics have an organic evolution

The dna in a cell’s nucleus encodes proteins that are eventually targeted to every membrane and compartment in the cell, as well as proteins that are targeted for secretion from the cell. for example, consider these two proteins: phosphofructokinase (pfk) is an enzyme that functions in the cytoplasm during glycolysis. insulin, a protein that regulates blood sugar levels, is secreted from specialized pancreatic cells. assume that you can track the cellular locations of these two proteins from the time that translation is complete until the proteins reach their final destinations.for each protein, identify its targeting pathway: the sequence of cellular locations in which the protein is found from when translation is complete until it reaches its final (functional) destination. (note that if an organelle is listed in a pathway, the location implied is inside the organelle, not in the membrane that surrounds the organelle.)
