Job Outlook. Employment of radiologic and MRI technologists is projected to grow 9 percent from 2014 to 2024, faster than the average for all occupations. As the population grows older, there will be an increase in medical conditions that require imaging as a tool for making diagnoses.
Activity 1 - DNA Extraction. We will extract DNA from fruit to investigate how it looks and feels. This procedure is similar to what scientists have to do before they can use the information contained in this DNA.This information can be used to improve crops so that they are more resistant to disease, insect invasion or changes in climate. Filter the fruit mixture through the cheese cloth. 2  Combine solutions from all student groups at this point. 3  Let the solution drain 5 minutes. 4  Using the large transfer pipettes, aliquot approximately 2 ml of the kiwi/strawberry fruit solution into a test tube, one for each pair of students.
Answers. Best Answer: DNA extraction procedure: See number 8 re:chloroform 1.Treat 25 mg of tissue with Proteinase K by adding 20 ml of stock PK solution (20 mg/ml) and 180 ul water. Function: proteinase destroys protein. 2.Let sit at 55 degrees for at least 1 hour.unction: separates aqueous (top) and phenol (bottom) layers. 7.Remove upper aqueous layer (CONTAINS DNA) to a new tube. 8.Add 200 ul of chloroform to aqueous layer (IN HOOD). Function: removes excess phenol from DNA. 9.Cap tub; mix well by inverting. Function: sets an emulsion; biphasic solution.
