C. mutations in the genes that code for proteins in this pathway have been linked to various types of cancer (ie ras-pancreatic, braf-colorectoal, mek-melanoma, egfr-lung). if you were developing a new cancer drug, what would be an appropriate target protein for the new drug therapy? justify your answer.

The mutated protein would be the target for the new drug therapy.

Explanation:

Cancer occur due to mutation in some important genes that regulate cell cycle as well as cell division.The mutation of tumor suppressor gene such as retinoblastoma,p53,PTEN etc also leads to the onset of cancer.

      Now the most important point to note that mutation in the these particular genes result in the formation of abnormal proteins or disease causing proteins.These mutated proteins are the principle cause for the occurrence of cancer.

        As a result the mutated protein would be appropriate target for the new drug therapy .The drug will interact with the mutated protein and blocks the toxic activity of the later.

option number one would be youre best option

the correct answer is - d. china has a large and growing population.

the fact that china has a large (the biggest) population, and it is still growing, doesn't hinder the agriculture production in the country. in fact, it can for increased production in the agriculture, since there's more labor force, as well the sheer mass of people produces lots of scientists that come up with new inventions as to how to improve this sector. nice example is the inner mongolia region in china, in general dominated by the gobi desert, but few scientist came up with a nice idea as to how to make the region productive by using plants that are very resistant to droughts, so lots of people have been employed, and the region is becoming greener and greener each year, and the production of food in this region is also increasing.
