Question: Which of the following is/are true for how proteins recognize DNA, RNA and other proteins? Need Assignment Help? (Select all that apply): Group of answer choices The specificity of interaction between protein and RNA is based mostly on the shape and chemical properties of the RNA instead of its sequence. The interaction of proteins with RNA is most similar to how proteins interact with proteins. Helix-turn-helix proteins represent the most abundant DNA-recognition domain in eukaryotic cells. Protein-protein interactions are more simple than protein-DNA interactions due to the lower number of polar, or hydrophilic, regions between the two interacting parts. In a helix-turn-helix motif, one helix holds the protein against the DNA backbone so that the other helix, termed the recognition helix, fits into the major groove of the DNA and interacts with the exposed edges of the DNA bases.
