Proteins that interact with DNA often interact with the phosphates that are part of this molecule. Which of the following types of amino acids would you predict to be present in the DNA binding sites of these proteins?

a. acidic amino acids
b. nonpolar amino acids
c. uncharged polar amino acids
d. basic amino acids

Option D) basic amino acids

Explanation:

Since the phosphates occupying the 5' end of DNA bear negative charge due to the previous dissociation of hydrogen atoms, ONLY portions of the interacting protein bearing positive charge serve as binding sites.

These portions of proteins with positive charge is made up of basic amino acids like lysine and arginine, as they have an extra amino acid in their side chain, and are attracted to phosphate molecules with negative charges.

Thus, basic amino acids will serve as binding sites

well for one plants are always the producer, so a is the answer. a wolf is more of the consumer(predator) and the deer is the prey so i know those two are out of the question. also mushrooms are fungi/fungus so a is the producer.
