Explanation of Solution

The features that characterize animals are -

  1. Heterotrophic nutrition - no animal can make its own food; they need to acquire nutrition by consuming other organisms.
  2. Multicellular, eukaryotic body - all animals are multicellular, even if the cells are not organized into organs.
  3. Locomotion - most animals move at some point in their life, at least during the larval stages.
Conclusion

Heterotrophic nutrition, multicellular body and locomotion are the three defining characteristics of animals.

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. Incubate both tubes in a 37 C water bath for 5 minutes.   Questions: 1)What is the selectable marker in this experiment? How…
