Unraveling the Mystery: A Lesson on DNA Replication

Unraveling the Mystery: A Lesson on DNA Replication

Learning Objective

Understand the process of DNA replication and its significance in cell division and inheritance.

What do you already know about DNA replication?

Slide 1: Introduction to DNA Replication

DNA replication is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules.

Slide 2: Importance of DNA Replication

DNA replication is essential for cell division, growth, repair, and passing genetic information from parent to offspring.

Slide 3: The Steps of DNA Replication

1. Initiation 2. Unwinding 3. Elongation 4. Termination

Slide 4: Initiation of DNA Replication

Initiation begins at specific sites on the DNA molecule called origins of replication.

Slide 5: Unwinding of DNA

Enzymes called helicases unwind the double helix structure of DNA to expose the individual nucleotides.

Slide 6: Elongation of DNA Strands

Enzymes called DNA polymerases add complementary nucleotides to each of the original DNA strands.

Slide 7: Termination of DNA Replication

The replication process is terminated when the entire DNA molecule has been copied.

Slide 8: Recap and Discussion

Review the key steps of DNA replication and its significance, then open the floor for questions and discussion.

Write down 3 things you learned in this lesson.

Have students enter three things they learned in this lesson. With this they can indicate their own learning efficiency of this lesson.

Write down 2 things you want to know more about.

Here, students enter two things they would like to know more about. This not only increases involvement, but also gives them more ownership.

Ask 1 question about something you haven't quite understood yet.

The students indicate here (in question form) with which part of the material they still have difficulty. For the teacher, this not only provides insight into the extent to which the students understand/master the material, but also a good starting point for the next lesson.
