Answer
DNA is organized into chromosomes through a series of packaging levels involving histones, nucleosomes, and higher-order structures.
Solution
a
DNA double helix: The fundamental structure of DNA is a double helix formed by base pairs of nucleotides
b
Histones: DNA wraps around histone proteins to form nucleosomes, which help in the compaction of DNA
c
Chromatin: Nucleosomes are further organized into a fiber known as chromatin, which can exist in a less condensed form called euchromatin or a more condensed form called heterochromatin
d
Chromosome structure: Chromatin fibers further loop and fold to form the characteristic X-shaped structure of chromosomes that is visible during cell division
Key Concept
Chromosome packaging
Explanation
DNA is compacted into chromosomes through interactions with histone proteins, forming nucleosomes and higher-order chromatin structures, culminating in the recognizable chromosome shape during mitosis.
