6) Histones are proteins found in eukaryotic cell nuclei, tightly bound to DNA, which has many phosphate groups. The isoelectric point (pl) of histones is very high, about 10.8. What types of amino acid residues must be present in relatively large numbers in histones? (1 point)

Step 1
The question asks about the types of amino acid residues that must be present in large numbers in histones, given that histones have a high isoelectric point (pI) of about 10.8 and bind tightly to DNA, which has many negatively charged phosphate groups. Show more…
