Transferring Genetic Information

What is DNA? (page A102)

• DNA is the differences between individuals of the same species.

• DNA is the material that makes up genes and determines traits.

• DNA is the process of selecting a few organisms with desired traits to serve as parents for the next generation.

• DNA is a diagram showing the gene combinations that might result from a genetic cross.

DNA has the shape of a _________________? (page A102)

The sides of the DNA ladder are made of what 2 items. (page A102)

• Adenine and Guanine

• Thymine and cytosine

• ribosomes and adenine

• Sugars and phosphates

What contains the coded information that DNA holds? (page A102)

All organisms use DNA in what three ways? (page A103)

• The same shape, the same four bases, and the same type of coded information.

• The same shape, the same size, the same ladders.

• The same size, the same sugars, the same information.

• The same four bases, the same height, and the same weight.

Name the four different bases. (page A103)

When the bases pair up, they always pair up in the same way. (page A103)

• Adenine pairs with cytosine.

• Guanine pairs with cytosine.

• Thymine pairs with adenine.

• Thymine pairs with guanine.

When cells copy their DNA to pass it on to offspring this is called__________? (page A104)

Replication begins when the two sides of the double-helix "ladder" do what? (page A104)

• Attach to other DNA ladders.

• Break apart into many small ladders.

• Separate, much like a zipper coming unzipped.

• Separate, much like oil and water do when mixed together.

DNA stores instructions for what two things? (page A104)

• Cell structure and function.

• Replication and RNA.

• Eye color and hair color.

• Cells shape and size.
