Which of the following statements is true regarding a basic amino acid? the positively charged r group of a basic amino acid could bind dna. all of these choices are correct. the hydrophilic r group of a basic amino acid will be located in the interior of a protein. a basic amino acid would be considered both polar and hydrophobic. the r group of a basic amino acid would only be able to form covalent bonds with other molecules.

Answer is A. The positively charged R group of a basic a.a could bind to DNA.

Basic amino acids have a positive charge and acidic amino acids have a negative charge. DNA also has negative charge because of the phosphate group in nucleotides. So they have opposite charges and can form ionic bonds.
Hope this helps:)

The scientific method is a series of steps followed by scientific investigators to answer specific questions about the natural world. it involves making observations, formulating a hypothesis, and conducting scientific experiments.the steps of the scientific method are •observation-the first step of the scientific method involves making an observation about something that interests you•question-once you've made your observation, you must formulate a question about what you have observed. •hypothesis-once you've made your observation, you must formulate a question about what you have observed. •experiment-once you've developed a hypothesis, you must design and conduct an experiment that will test it.•results-the results are where you report what happened in the experiment. •conclusion-the final step of the scientific method is developing a conclusion.i hope that this you : )
