Mutation Practice

The survival of a species depends on its ability to adapt to changes in the environment. A species must be capable of surviving and reproducing despite changes to food sources, climate, or threats from predators. Which statement correctly describes a way that mutations increase the likelihood that a species will survive in a changing environment?

• F

• G

• H

• J

In the 1960's, the molecular biologist George Streisinger developed the strand-slippage hyposthesis. Streisinger noticed that mutations occurred in areas of DNA that contained many repeated sequences. When a strand-slippage error occurs, an insertion mutation can result. How does the insertion mutation affect the DNA?

• B

• C

• D

A mutation in which types of cells would only affect the organism and not future generations?

• F

• G

• H

• J

A certain mutation in the gene for hemoglobin results in the red blood cells becoming sticky, rigid, and irregularly shaped. These irregularly shaped red blood cells block the flow of blood throughout the body. A single base mutation is responsible for these irregularly shaped blood cells.

Which of these mutations most likely results in the mutated hemoglobin gene?

• F

• G

• H

• J
