Choose incorrect statements from given characters of DNA and chromosome:

(i) Length of DNA double helix in a typical mammalian cell is calculated by multiplying the total number of bp with distance between two consecutive bp.

(ii) The length of DNA double helix in a typical mammalian cell is approximately 2.2 metres.

(iii) The dimension of a typical nucleus is approximately 10 -6 m and it is larger than length of DNA.

(iv) In prokaryotes, DNA present in ‘nucleoid’ where DNA is organized in large loops held by proteins.

(v) In prokaryotes, negatively charged DNA is wrapped around the positively charged basic histone proteins octamer to form a structure called nucleosome.

(vi) Histones are rich in the basic amino acid residues lysines and arginines and both the amino acid residues carry positive charges in their side chains.
