Question

1.Analyze the steps used to prevent mutations when a cell is stressed. Use the p53 gene as an example in this process.
2.Describe the role that tumor suppressor genes play in cancer prevention and in cancer promotion. Provide an example of a tumor suppressor gene and the cancer that results if proper functioning ceases.
3.Highlight the economic, cultural, and technological changes associated with a more globally connected world.
4.Some vestigial structures persist because they may still have slight function or did in the very recent past. Wisdom teeth, which erupt in early adulthood and often have to be removed because they do not “fit” in a modern person’s jaw, are sometimes considered vestigial, but they may have had a function in the recent past. Why might wisdom teeth have persisted over the course of human evolution?
5.Explain the reasons why within six months of effectively using methicillin to treat S. aureus infections in a community, all patients newly infected with S. aureushave MRSA.
6.Describe the reason why the scientific method is the basis for scientific discovery and the role that it plays in creating sound and reliable theories.

Explanation / Answer

1.According to given data, p53 gene is a tumour suppressor gene which prevent growth of cancer cells .Cells under different stress condition like nutrient deficiency,salt ,pH etc starts adaptation and stimulate the expression of certain genes that protein help in the cope up about the situation.

2.Gene like p53,Rb gene are the tumour suppressor gene which prevent the growth of cancer cells when present in dominant expression.Mutation in these genes change their function anl lead to the development of cancer in body.Example -lung cancer,breast cancer.

3.In the globally connected world ,there is exchange of ideas,researches among peoples of distant location.it is beneficial for the betterment of a nation in respect to economic, cultural and technological aspects.

4.In the past time,there is wisdom teeth present in individual during the adulthood but they are eliminated as the passage of time.Wisdom teeth are 3rd set of molars present in the backside of our mouth and need to be surgically removed as they can trapped into the jawbone or gums and can cause pain.Their main in our ancestor is that they feed on roots ,stems etc and thus they evolve.

5.Staphylococcus aureus develop resistance to the methicilin,when they are treated with more time.methicilin resistant Staphyloccus aureus (MRSA) is resistant to many antibiotics.There is a mecA gene which confers resistance to methicilin by making a penicillin binding protein.

6.Scientific discovery is based on analytical studies involving experiment ,it's observation and the analysis which is basis for the scientific method ,it's liability.It explain the whole aspect of a theory in terms of its procedure,factors and result .Scientific discovery makes a full flesh theory in term of all aspects.
