1 The addition of a phosphate group by a protein kinase is a key regulatory switch for many biological processes. How can regulation be achieved by this simple mechanism?
2 The smallest component of an element that still has properties of the element is called a(n):
3 The elemental composition of the universe, Earth's crust, and the human body differ sharply. What factors might contribute to these differences?
4 Which of the following terms does NOT refer to an example of a weak force of interaction between two biological molecules?
5 The availability of elements in the environment does not by itself guarantee selection for living cells. This is because elements used for making the molecules of living systems must be:
