D. Question 54 2 pts The Central Dogma of Biology can be stated as O proteins RNA DNA. RNA DNA proteins DNA-→ proteins RNA. DNA RNA proteins.
U Question 55 2 pts In an experiment described in a biology lab book, the instructions state that five minutes after two chemicals (A and B) are mixed, chemical B will be oxidized and chemical A will be reduced. This means that O chemical B has lost electrons to chemical A chemical B has gained electrons from chemical A. chemical Bhas lost its ability to interact with chemical A. B O chemical B has shared electrons with chemical A
