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.

creative diagnostics provides a protocol for total protein extraction based on ripa which is widely used.

tsd is temerature dependent sex determination.

tsd: it is a type of environmental sex determination in which the temperature experienced during embryonic/ larval development (ambient temperature for development) determine the sex of the offspring.

crocodile displays the tsd where the ambient temperature of the developing egg determines the individual's sex. for example in the american alligator's eggs, incubation at 33 ºc produces mostly males, while incubation at 30 ºc produces mostly females. so if the american alligator's egg will get the ambient temperature (33 degree celcius)during embryonic development from egg, the offspring will be male and same for the female sex determination.
