__________ in the DNA helix provide DNA-binding proteins access to base sequences buried in the center of the molecule, so that proteins can interact with the bases without the strands being separated.

Question

Quizplus · Accepted Answer

The grooves in the DNA helix, specifically the major and minor grooves, provide access to the base sequences for DNA-binding proteins without separating the strands. This is because the edges of the bases are exposed in the grooves, while they are covered in the center of the helix. The other choices, breaks, nicks, attractions, and repulsions, do not relate to this aspect of DNA-binding protein access to base sequences.
