Lesson: DNA in Eukaryotes Biology

In this lesson, we will learn how to describe the structure of chromosomes in eukaryotic cells and explain the role of histones and nucleosomes in forming chromosomes.

Lesson Plan

Students will be able to

define the terms chromosome, chromatin, and nucleosome,
describe how DNA coils around histones and condenses to form chromosomes,
recall that chromosomes appear differently depending on the stage of the cell cycle.
