You decide to use RT-PCR to confirm your predictions about the exon organization of the 2 mRNAs in tissue such as heart and epidermis. Describe in general the experiment you would do, specifying where your PCR primers would be designed to bind. What results would you expect. Please be specific

Part A What biological and psychological factors cause people to abuse opioids? Please incorporate information on the endogenous opioid receptors in your discussion of biological factors. Part B Read the article below on vaccines for opioid addiction. What are your reactions after reading the article? Are you in favor of promiting vaccines for opioid addiction? Support your decision with facts from the article and other scholarly sources.

what is an exome ? why can exome sequencing be more informative than genome sequencing for investigating the genetic basis of trait?

By gel electrophoresis, how do you know if your protein binded to the column? How would you modify the purification next time to make it more efficient?

Calculate the amount of reagent and water required to make the following solutions. Do not assume you have a stock solution unless instructed to do so.

a) 1.00 L of 20.00mM Tris-HCl, 50.0mM NaCl, 20.00mM MgSO₄ x 7H₂O, 5.00mM CaCl₂

b) 275 mL of 25% Na₂HCO₃, 18.0% EtOH

c) 750.0mL of 0.2M sodium citrate, 10.00mM SDS (from 0.50M stock), 2.5% glycerol

d) Calculate molarity of 15% NaCl and 27% hydrochloric acid

Based on what you know about anole morphology and the process of adaptation via natural selection, do you think it is possible for a generalist anole to be as adept as each of the specialist anole ecomorphs at living (for example: climbing, running, hunting, etc.) in the different island habitats? In other words, do you think it is possible for a single anole species to be as good at living on twigs as the twig ecomorph anoles, and as good at living on trunks as the trunk ecomorph anoles, and as good at living on the tops of trees as the trunk-crown ecomorph anoles, etc.?

List the three variations of carbon-fixation reactions (C3, C4, and CAM) and write their basic characteristics (locations or times of C4 and C3 pathway in each) with one or two examples for each.

What sets the limits on the stimuli that an animal can sense? What limits the movements an organism makes? How do sensory and motor systems compare across different types of animals?

2. What information does the Ramachandran plot provide and what are its implications for protein folding?

a) What is a sensory system designed to do?

b) What is the relationship between sensation and perception? What is the role of experience in creating this relationship?
