Question

Quizplus · Accepted Answer

HMG proteins are small conserved proteins containing about 50% charged amino acids. They are also able to alter DNA conformation by causing it to bend, unwind, and form loops, which makes them architectural proteins that regulate gene expression. However, they are not moderated by the trp attenuation leader sequence. Therefore, choices I, III, and IV are correct, while choice II is incorrect. Therefore, the best choice is D.

HMG Proteins Are (I)a Set of Small Conserved Proteins Containing About 50% Charged
