The best description of how regulatory proteins recognize and bind to the correct sequences without unwinding the DNA double helix is...A) DNA-binding domains can recognize the chemical groups that protrude from the base-pairs into the major groove.B) DNA-binding domains can recognize the chemical groups that protrude from the base-pairs into the minor groove.C) DNA-binding domains can recognize the chemical groups that protrude from the sugar-phosphate backbone into the major groove.D) DNA-binding domains can recognize the chemical groups that protrude from the sugar-phosphate backbone into the minor groove.E) Regulatory proteins have DNA-binding domains that are inserted into the major groove and can recognize the shape of each nitrogenous base.
