Liminating Microbes and DNA is a Simple Molecule

Part 1
Eliminating Microbes

Course Objective:

a?Understand the composition and function of the major macromolecules of the cell.a?

In Chapter 3, a?Questions to Consider,a? page 56 of your textbook is this question-

Suppose you had the option of destroying one type of organic compound in a bacterium as a way of eliminating the microbe. Which type of compound would you choose and why?

The Question for you to answer and discuss is:

Which type of compound (proteins, lipids, carbohydrates, or nucleic acids) would you choose and why?

Part 2
DNA is a Simple Molecule

Course Objective:

a?Explain how the sequence of bases in the DNA molecule serves as a genetic code and how this code is transcribed to a messenger RNA molecule and then translated to a sequence of amino acids in a protein molecule.a?

In Chapter 4, a?Questions to Consider,a? page 85 of your textbook is this question-

In one sense, DNA is a relatively simple molecule, having only four different subunits. And yet, DNA can specify extraordinarily complex proteins having at least 20 different amino acids in chains of many thousands or more. How does DNA accomplish this seemingly impossible task?

The Question for you to answer and discuss is:

How does DNA accomplish this seemingly impossible task?
