1Alpha helices can focus large electric fields at the protei

1)Alpha helices can focus large electric fields at the protein’s ________ ________ to affect catalysis by lowering the energy of the activation state.

2)Which of the following sequences can fully base-pair with itself?

A) 5’ CAGCAGCA 3’

B) 5’ AATCCAAT 3’

C) 5’ GGGGTTTT 3’

D) 5’ CGCCGGCG 3’

Solution

1)1)Alpha helices can focus large electric fields at the protein’s active site to affect catalysis by lowering the energy of the activation state.

Reason:Active site of enzymes that are proteins interact with molecules to form transition states that lower the activation energy and help in catalysis.

2) The correct answer is : D) 5’ CGCCGGCG 3’

Reason: 5\' CGCC 3\'

3\' GCGG 5\'
