Chromatin and chromosomes

Unit 1 4ESO Bilingüe

1. CHROMATIN AND CHROMOSOMES

2. Chromatin is the complex of DNA and proteins found in the eukaryotic nucleus

3. Chromosome is packaged and organized into 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

6. FROM DNA AND CHROMATINE UNTIL CHORMOSOME

7. Chromosome A natomy

8. 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.

9. ACTIVITY: What are the differences between chromatin and chromosomes?
