Short Answer

Expert verified

The correct option is D.

Step by step solution

01

Step. 1 Introduction

02

 Step. 2 Explanation for Correct option.

The chromosomes to the same deoxyribose acid nature in a pair of chromosomes are identical.

03

Step. 3 Explanation for Incorrect option. 

Option a. Histones attach to Genetic material, helping to form chromosomes and govern gene activity.

Option b. Nucleosomes are the fundamental DNA packing units composed of histone proteins upon which Genetic material is wrapped.
