What type of amino acids would you expect to be included in the regulatory alpha helix based on its change in position?The helix would contain basic (positively charged) amino acids, such as lysine, arginine, and histidine.The helix would contain polar, uncharged amino acids such as serine and threonine.The helix would contain hydrophobic ...

33. Why do positively charged amino acids appear more often than usual in histone proteins? Because histones have a higher molecular mass, which improves DNA compaction Because histones are strongly attached to the positively charged phosphate backbone of DNA Because histones and DNA have opposite charges, which improves the compaction of DNA into

The common amino acids can be categorized as positively charged, uncharged, or negatively charged based on their charge under physiological conditions. What do all of the negatively charged amino acids have in common? Select the correct answer below: O Their side chain (R group) contains an amino group. O Their side chain (R group) is aromatic.
