A - Histone octamer, C - DNA
A- Histone octamer, C - h1 histone
B - H1 histone, C - Histone octamer
A - H1 histone, B- DNA
The figure shows the packaging of DNA. It represents a nucleosome, where A is the DNA, B is the H1 histone and C is the histone octamer. The DNA wraps around the octamer, held at position by the H1 histone and further condenses to form chromosomes.
