UNIT 3: MOLECULAR GENETICS [Thinking

Read the enclosed article and explain how the points raised in it could impact vou. vour diet and your lifestyle.

1. Be sure to address how it could impact DNA. protein synthesis. and other cellular processes

2. create a summary table about the ethical concerns raised from this article

-What proteins/signaling molecules are inhibited and/or promotedby ecstasy?

-What cellular processes are impacted as a result of ecstasyinteracting with the proteins/signaling molecules mentioned in theabove question?

Our understanding of genetic inheritance and the function of DNA in producing the characteristics of the individual have been developing for more than 150 years. Consider our current state of knowledge. Link genetic characteristics to DNA structure. Explain how DNA through the process of protein synthesis is responsible for the ultimate expression of the characteristics of the organism. Describe how interference in protein synthesis can result in disruption of cellular and bodily processes? How does the significance of one class of proteins, the enzymes, relate to the importance of proper nutrition throughout life?

What causes Phenylketonuria at the molecular level.

1. What molecule(s) are involved,

2. How does the mutation affect the function of the protein and why it does (give your answer in molecular terms – i.e. use molecules to explain it)

3. How does the mutant molecule affect the other cellular molecules – i.e. how could this mutation account for the symptoms of the disease.
