“DNA and RNA, Genes, Mutations, and Gene Therapies”
Â· Examine three (3) differences between DNA and RNA then explain two (2) main reasons why DNA is the most favorable molecule for genetic material. Next suggest how RNA compares to DNA in regards to genetic material.
o Go to The Guardian website and read the article titled â€œMind-control device lets people alter genes in mice through power of thoughtâ€ found at (https://www.theguardian.com/science/2014/nov/11/mind-control-device-alter-genes-mice). Next discuss three (3) main points of the article you found most significant then explain two (2) ways the article you read relates to this weekâ€™s lesson. Provide examples of this relation with your response.
o Mutations are the original source of genetic variation. Explain how mutations can be either beneficial or harmful then provide an example for each. Next identify a disease, which is caused by a mutation, and then describe the biological basis of your chosen disease. In your response be sure to note the exact disease causing mutation.
o Briefly describe the biology behind DNA-based Vaccines and Gene Therapy. Next suggest what you believe are the major similarities and differences between these two (2) therapies. Which do you believe is the best option? Justify your response.

Â· Name two (2) similarities and two (2) differences between mitosis and meiosis I and II. Next state three (3) benefits of genetic variation which result from meiosis. Which benefit do you believe is most significant? Justify your response.
Â· Read the Journal of Oral and Maxillofacial Pathology article entitled, â€œMitosis at a Glanceâ€ which is found at (www.ncbi.nlm.nih.gov/pmc/articles/PMC4211232/).
