The complex exercise "Sunscreen" focuses on the cell cycle and the identical replication of DNA. With this student knowledge as a prerequisite, this complex exercise investigates why sunscreen is important, how it works, and what it protects us from.  

This exercise can be used to consolidate knowledge on the cell cycle, to prepare for an upcoming exam or as an exam itself.

The complex exercise is tailored to require 90 minutes of work time.

Proposed solutions and references to the following competencies are included:

-        I can describe the molecular structure of DNA.

-        I can describe the course of mitosis (phases + their functions as well as the genetic configuration of the nucleus).

-        Using specific examples, I can illustrate the importance of mitosis for the survival of an organism.

-        I can explain the importance of DNA replication for the course and the outcome of mitosis.
