Biology · CELL THE UNIT OF LIFE

In a diploid human somatic cell, approximately two metres of DNA is packaged within the nucleus into 46 chromosomes. What is the fundamental biochemical composition of interphase chromatin?

1. A
   DNA wrapped around acidic albumin proteins along with lipids, devoid of any RNA.
2. B
   DNA, basic proteins called histones, some non-histone proteins, and RNA.
3. C
   Only double-stranded circular DNA and structural polysaccharides without associated proteins.
4. D
   Single-stranded RNA, acidic non-histone proteins, and divalent calcium pectate fibrils.
