The complex exercise "Forever Young" focuses on the identical replication of DNA and the cell cycle. With this student knowledge as a prerequisite, the complex exercise "Forever Young" investigates the influence of telomeres on cell aging, their connection with the triggering of apoptosis, and the potential use of telomerases to combat aging and age-related diseases. 

This exercise can be used to consolidate knowledge on the identical replication of DNA, 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 organizational levels of DNA, and I can attribute their occurrence to certain events in the cell cycle.

-        I can describe the course of identical replication of DNA, and I can explain its semiconservative nature.

-        I can describe the course of mitosis.

General Competencies:

-        I can verbally present an object/process adhering to spatial/temporal criteria of order ( (describe).

-        I can make (a) fact(s) or circumstance(s) clear by describing the involved elements and pointing out causal correlations between them ( explain).

-        I can trace back a circumstance to a rule, biological law or causal correlation ( give reason)

-        I can give judgment by myself that is based on facts and logical conclusions ( evaluate).

-        I can reproduce acquired knowledge in a structured, coherent, selective way in a manner suitable to the audience.
