Textbook Question
Chapter 24, Problem 8TYU
SCIENTIFIC INQUIRY • DRAW IT In this chapter, you read thut bread wheat (Triticum aestivum) is an allohexaploid, containing two sets of chromosomes from each of three different parent species. Genetic analysis suggests that the three species pictured following this question each contributed chromosome sets to T. aestivum. (The capital letters here represent sets of chromosomes rather than individual genes, and the diploid chromosome number for each species is shown in parentheses.)
Evidence also indicates that the first polyploidy event was a spontaneous hybridization of the early cultivated wheat species T. monococcum and a wild Triticum grass species. Based on this information, draw a diagram of one possible chain of events that could have produced the allohexaploid T. aestivum.

As a medical professional, it is important to be able to discuss how genetic processes such as translation regulation can directly affect patients. Think about some situations that might involve translation regulation.
Respond to the following in a minimum of 175 words:
Why is translation regulation important?
What are some examples of translation regulation in humans?
Select one of the examples you provided and explain what happens when translation regulation goes wrong.
The metabolic pathway below is used for the production of the purine nucleotides adenosine monophosphate (AMP) and guanosine monophosphate (GMP) in eukaryotic cells. Assume each arrow represents a reaction catalyzed by a different enzyme. Using the principles of feedback inhibition, propose a regulatory scheme for this pathway that ensures an adequate supply of both AMP and GMP, and prevents the buildup of Intermediates A through G when supplies of both AMP and GMP are adequate.

The relative motion between the plates is indicated by the half arrows along the transform plate boundary (i.e., the Pacific Plate is moving to the northwest relative to the North American Plate). Note the two bodies of Oligocene volcanic rocks (labeled Ov) on the map in the previous page located along either side of the San Andreas Fault. These rocks are about 23.5 million years old and were once one body of rock. They have been separated by displacement along the fault. 21. Based on the offset of these volcanic rocks, what is the average annual rate of relative plate motion in cm/yr?
