Chromatin is the complex of DNA and proteins found in the eukaryotic nucleus. Chromatin is packaged and organized into chromosomes. DNA is wrapped around histone proteins forming nucleosomes to efficiently package the DNA into chromosomes, which make up the full genome of an organism.

3. Chromosome is

chromatin.

4. • The structure of chromatin depends on the stage of the cell cycle

5. Structure of Chromosomes
• DNA is wrapped around histone proteins forming nucleosomes.
Histones are protiens that
are going to help package the
DNA more eficciently

CHORMOSOME

7. Chromosome Anatomy

9. Genome
• the genome is the genetic material of an organism, in others words is
an organism’s complete set of DNA, including all of its genes.
The basic number of chromosomes in the somatic cells of an
individual or a species is called the somatic number and is
designated 2n. In humans 2n = 46.
