Question
Chapter 29, Problem 12P
Interpretation Introduction
Interpretation:
To determine the significance of two Mg2+ ions in RNA polymerase II active state.
Concept introduction:
DNA or Deoxyribonucleic acid is a molecule made of two chains which coil around one another. These form a double helix which carries instructions genetical in nature like related to reproduction, growth, development, functioning of the living organisms.
There are two Mg2+ ions that are present in the RNA polymerase II active state.

You’ve isolated a protein and determined that the Native molecular weight of the holoenzyme is 160 kD using size exclusion chromatography. Analysis of this protein using SDS-PAGE revealed 2 bands, one at 100 kD and one at 30 kD.
The enzyme was found to be 0.829% NAD (by weight). What further can be said regarding the structure of the polypeptide?
