What is the order of packaging of chromatin in eukaryotic cells from smallest to largest size?
A)double-helix → solenoid → nucleosome → chromosome
B)double-helix → chromatin → solenoid → chromosome
C)single-stranded DNA → chromatin → histones → chromosome
D)double-helix → nucleosomes → solenoid → chromosome

Question

Quizplus · Accepted Answer

The correct order of packaging of chromatin in eukaryotic cells is double-helix, nucleosomes, solenoid, and chromosome. The double helix is the basic unit of genetic material, which is then wrapped around histone proteins to form nucleosomes. These nucleosomes then fold into a more compact structure called the solenoid. Finally, the solenoid forms the characteristic X-shaped chromosome during cell division. Therefore, option D is the correct order of packaging of chromatin in eukaryotic cells from smallest to largest size.
