Overview

Welcome, this week we will be studying the structure and function of DNA. Topics for this module include the history of our understanding of DNA including the experiments that provided evidence that DNA was the heredity material of cells, the structure and sequencing of DNA, the basis of DNA replication, DNA replication in eukaryotes and prokaryotes, and how DNA is repaired.

Note: There are no more APA in-text citation assignments to complete this semester. You should use the extra time you have in your week to start building your Final Presentation Assignment and Critical Thinking Essay Assignment. Use your scored rubrics and comments from your APA in-text citation assignments to build your final assignments and make sure turn them in to Canvas before the end of the semester.

By the end of this module you should be able to do the following:

Chapter 14

Explain transformation of DNA
Describe the key experiments that helped identify that DNA is the genetic material
State and explain Chargaff’s rules

Describe the structure of DNA
Explain the Sanger method of DNA sequencing
Discuss the similarities and differences between eukaryotic and prokaryotic DNA

Explain how the structure of DNA reveals the replication process
