你将学到什么

The key secret of life in the universe

DNA Structure

How atoms combine to make molecules

How great scientific discoveries are made

课程概况

In this chemistry course, you will learn about “Life in the Universe.” We will explore DNA as genetic material and atoms as the building blocks of life. We will discuss the discovery and key features of the double helical structure of DNA and the chemical principles behind the sugar-phosphate backbone and hydrogen bonding in the base pairs will be emphasized. We will also discuss identification DNA as genetic material.

At the end of the course, you will learn how and why atoms are bonded to make molecules such as DNA and the discovery of argon will be used to explain the valency and reactivity of different elements based on the periodic table.

To help learners better understand the material, we will be referencing Nobel lectures and scientific papers such as:

Watson and Crick’s 1953 paper in Nature
Rayleigh’s 1904 Nobel Lecture on the discovery of argon
The 1944 paper in J. Experimental Medicine by Avery, MacLeod, and McCarty
Perrin’s 1928 Nobel Lecture

课程大纲

Week 1: Structure of DNA
Week 2: Genetic Material
Week 3: Atomic Theory
Week 4: Periodic Table
