NEETZoologyMolecular Basis of Inheritance
Select the incorrect statement for the given figure.
Options
- AThere is a set of positively charged, basic proteins called histones.
- BA protein acquires charge depending upon the abundance of amino acids residue with charged side chains.
- CHistones are rich in the basic amino acid residues lysine and arginine.
- DBoth the amino acid residues carry negative charges in their side chains.
Correct answer
D. Both the amino acid residues carry negative charges in their side chains.
Step-by-step solution
In eukaryotes, this organisation is much more complex. There is a set of positively charged, basic proteins called histones. A protein acquires charge depending upon the abundance of amino acids residues with charged side chains. Histones are rich in the basic amino acid residues lysine and arginine.Both the amino acid residues carry positive charges in their side chains. Histones are organised to form a unit of eight molecules called histone octamer.
