Choose correct statements about recognition mechanism of TBP ;

A. TBP causes the minor groove to be widened to an almost flat conformation

B. It also bends the DNA by an angle of ~120o

C. The interaction between TBP and DNA involves maximum number of hydrogen bonds between the protein and the edges of the base.

D. Much of the specificity is imposed by two pairs of phenylalanine side chains that intercalate between the base pairs at either end of the recognition sequence and drive the strong bend in the DNA.

Following statements are regarding to the heat production by the activation of sympathetic nervous system.

A. Activation is stimulation of β receptors in brown fat, which increases metabolic rate and heat production.

B. Activation is stimulation of α2 receptors in brown fat, which increases metabolic rate and heat production.

C. Stimulation of α1 receptors in vascular smooth muscle of skin blood vessels, producing vasoconstriction. Vasoconstriction reduces blood flow to the surface of the skin.

D. Stimulation of α1 receptors in vascular smooth muscle of skin blood vessels, producing vasodilation. Vasodilation reduces blood flow to the surface of the skin.

Which of the following combination is correct?
