Explanation The spinal cord can be defined as the cylindrical bundle of the nerve fibers and connected tissue. It is surrounded in the spinal region and joins approximately all the body parts to the brain. It forms the central nervous system with the brain. A spinal nerve: It can be defined as a mixed nerve, that carries sensory, motor, and autonomic signals or information between the spinal cord and the remaining body. In the human body, there are present 31 pairs of spinal nerves. These are located one on each side of the vertebral column. The two types of roots of a spinal nerve: Posterior root and Anterior root. Criteria for difference Posterior root Anterior root 1 ...

1) Look at the ideal results. Were your predictions accurate, and how did they compare with your results? 2) You used aseptic technique during this lab. Why is it important to work in a sterile manner when working with bacteria in the lab? 3) Why are the cells incubated at 42°C?

Overview of Transformation Protocol -Prepare competent bacteria for transformation: Treat starter E. coli bacteria with CaCl2and Competent Cell Solution (CCS). Store on ice until transformation procedure. Competent cells are cells that are likely to take up foreign DNA and be transformed. This step increases the likelihood that the E. coli cells will take up the introduced vector and be transformed. -Transformation procedure: Obtain two microcentrifuge tubes containing your competent cells. Label one tube +DNA and one -DNA. Add CaCl2 to both tubes. Add the transformation mix containing the plasmid DNA to the tube labeled +DNA. Do not add any plasmid DNA to the -DNA tube. Incubate both tubes on ice for 10 minutes. Then, place both tubes in a 42\deg C water bath for 45 seconds. Replace the tubes in an ice bucket for 2 minutes. Add recovery broth to both tubes.
