Exposure of which of the following regions of a molecule of DNA permits the reading of DNA sequence without opening the double helix?
A)Phosphate groups
B)Phosphodiester bonds
C)Major groove
D)Minor groove

Question

Quizplus · Accepted Answer

The major groove of the DNA molecule contains information about the specific sequence of nucleotides. The shape of the major groove allows proteins and enzymes to recognize and bind to specific nucleotide sequences without having to open the double helix. This allows for the reading of the DNA sequence without disrupting the overall structure of the molecule. The phosphate groups and phosphodiester bonds are important components of the DNA backbone but do not contain information about the nucleotide sequence. The minor groove is not typically used for reading the DNA sequence.
