The classic "beads-on-a-string" structure is the most decondensed chromatin structure possible and is produced experimentally. Which chromatin components are not retained when this structure is generated? Explain.

A. 30-nm fiber
B. linker DNA
C. nucleosome core particles
D. core histones
E. linker histones

E. linker histones

Explanation:

Nucleosomes are the basic unit of chromatin. These structures (nucleosomes) are composed of four core histones: Histone 2 A (H2A), Histone 2B (H2B), Histone 3 (H3), and Histone 4 (H4). Moreover, Histone 1 (H1) is a linker histone required in the compaction of the nucleosomes

the circled areas are referred to   as sunspots.   the sunspots are cooler than the   surrounding area.

sunspots are temporary phenomena on the photosphere of the sun that appear visibly as dark spots compared to surrounding regions. they correspond to concentrations of magnetic field flux that inhibit convection and result in reduced surface temperature compared to the surrounding photosphere.

actually the answer is c
