I assume this photo has the labels you are talking about.
DNA double helix consists of two strands that wind around each other with their nucleotides liked.-> it's the structure number 5
nucleosome- it's a segment of DNA wound in sequence around eight histones (proteins)- number 2
Histone- proteins with DNA around them, forming the nucleosome- number 4
Tight helical fiber- chromatin <span>coiled very tightly- 3
Cromosome- </span><span>chromatin condensed even tighter forming a X shape.- 1</span>
Cell Membrane is the answer
