Anion-exchange chromatography would best purify and concentrate a protein with a high percentage of aspartate and glutamate residues.
Anion-exchange chromatography separates chemicals based on their charges by utilizing an ion-exchange resin with positively charged groups, such as diethyl-aminoethyl groups (DEAE). The resin is covered with positively charged counter-ions in solution (cations). Anion exchange resins attach to charged molecules and dispense the counter-ion negatively. At higher pH levels, anion exchange chromatography is often used to filter proteins, amino acids, sugars/carbohydrates, and other acidic compounds having a negative charge. The intensity of the substance's negative charge determines the binding's tightness between the substance and the resin.
Thus, aspartate and glutamate, negatively charged amino acids would bind to the positively charged resin in the column.

Because muscle contractions often need to happen quickly, they are controlled via _____________ receptors.
Because muscle contractions often need to happen quickly, they are controlled via ionotropic receptors.
What is ionotropic?
A class of transmembrane ion channels known as ionotropic receptors respond to the binding of a chemical messenger (ligand), such as a neurotransmitter, by opening or closing the channels. Endogenous ligands often attach to LGIC protein complexes at an allosteric binding site, which is situated on a separate part of the protein than the ion conduction pore. The ion channel's activity is controlled by a ligand, and it typically exhibits high selectivity for one or more ions, such as Na+, K+, Ca2+, or Cl-.
Nicotinic acetylcholine receptors are the standard example of ligand-gated ion channels. It is made up of five protein subunits called pentamers, each of which has two cholinergic binding sites that, when occupied, change the receptor's structure and allow an internal pore to open.

Proteins that bind to DNA and RNA make up a sizeable portion of biological proteins and play crucial roles in cells. Controlling transcription and translation, DNA repair, splicing, apoptosis, and modulating stress responses are just a few of their duties.The functions of DNA are modulated by the hundreds of proteins that are present in our cells. Due to their ability to bind to DNA, these proteins are known as DNA-binding proteins. DNA-binding proteins perform a variety of tasks, including as regulating the synthesis of proteins, controlling cell growth and division, and storing DNA inside the nucleus.Adenine (A), cytosine (C), guanine (G), and thymine (T) are the four bases of DNA (T).

What is chargaff's rule?The molar ratios [A] = [T] and [C] = [G] were present in all species, and the ratio [C + G] / [A + T] was often lower than unity since [C + G] is a less common element. And Chargaff's rule name is given to these ratios.
Additionally, the molar similarities of A with T and C with G naturally support a certain type of combination link. Furthermore, Chargaff himself is unwilling to take a chance on claims of his experimental observation in the absence of new experimental ideas.
Additionally, he believed that Watson and Crick's model-building strategy was not grounded in science. Most notably, he later disparaged molecular biology in general and eventually grew frustrated at what he perceived as a refusal to acknowledge the significance of his work.
Therefore, in this case, 30% is Adenine and 30% will be Thymine, so the remaining 40% will be GC, out of which 20% will be Guanine.
