Prior Knowledge Questions (Do these BEFORE using the Gizmo.)

1. Suppose you want to design and build a house. How would you communicate your design

plans with the construction crew that would work on the house?

2. Cells build large, complicated molecules, such as proteins. What do you

think cells use as their “design plans” for proteins?

Gizmo Warm-up

Just as a construction crew uses blueprints to build a house, a

cell uses DNA as plans for building proteins. In addition to DNA,

another nucleic acid, called RNA, is involved in making proteins.

In the RNA and Protein Synthesis Gizmo, you will use both DNA

and RNA to construct a protein out of amino acids.

1. DNA is composed of the bases adenine (A), cytosine (C),

guanine (G), and thymine (T). RNA is composed of adenine,

cytosine, guanine, and uracil (U).

Look at the SIMULATION pane. Is the displayed segment a

part of a DNA or RNA molecule? How do you know?

2. RNA polymerase is a type of enzyme. Enzymes help chemical reactions occur quickly.

Click the Release enzyme button, and describe what happens.
