All cells require energy to live.You learned how cells generate and then utilize that energy through the metabolic process. For example, the aerobic and anaerobic respiration processes of various organisms have been harnessed by both the food and drinks companies and the waste/biofuels industries. Also, consider the impact of understanding the cause of a metabolic disease and the therapies we can use. Choose ONE of the areas mentioned above that you would like to learn more about and write two or three paragraphs describing the process and how it relates to metabolism within the cell. Provide at least one specific (named) example in your description and how our understanding of that particular disease/enzyme/cell type has been of benefit to us and if you consider the use of this knowledge to have a major impact on our everyday lives.

1.Select, copy and paste a region of DNA sequence from this CDKN2A gene with 800 bp containing the site of the mutation (let be in the middle).
2.How to AMPLIFY this 800 bp sequence and CONFIRM its expected size?
3.Explain the above AMPLIFICATION method in detail mentioning all steps and reaction ingredients.
4.Explain the above size CONFIRMATION method in detail mentioning all steps and reaction ingredients,to deduce the correct ORF from the mRNA sequence of the gene and underline the mutated amino acid.
*they are all for the same gene CDKN2A

discussed the Laws of Thermodynamics and their relation to energy and energy transfer. Energy transfers take place constantly in everyday activities. Think of two scenarios: cooking on a stove and driving. Explain how the second law of thermodynamics applies to these two scenarios.
