As an embryo develops, identical cells give rise to specialized cells that perform different functions. What statement best describes the role of RNA in the differentiation of a specialized cell? A. RNA synthesizes new genes, and then it transcribes and translates these new genes into proteins specific to the cell. B. Certain genes in the cell are transcribed into RNA molecules, which are then translated into proteins specific to the cell. C. RNA deletes regions of the DNA that are unnecessary to the cell, and then it uses the remaining DNA to make proteins. D. All genes in the cell are transcribed into RNA molecules, but only some of these molecules are translated into proteins.

Joe is breeding cockroaches in his dorm room. he finds that the average wing length in his population of cockroaches is 4 cm. he chooses the six cockroaches that have the largest wings; the average wing length among these selected cockroaches is 10 cm. joe interbreeds these selected cockroaches. from earlier studies, he knows that the narrow-sense heritability for wing length in his population of cockroaches is 0.6. a. calculate the selection differential and expected response to selection for wing length in these cockroaches. b. what should be the average wing length of the progeny of the selected cockroaches?

Ras is a g-protein that is activated when a growth factor attaches to egfr. its activation results in the replacement of a gdp molecule with a gtp molecule, thus allowing a signal transduction pathway to be activated. considering the signal pathway illustrated on this page, what is one potential outcome of a mutation in the ras gene that leads to ras protein hyperactivity. be specific.
