Amino acid

Multiple Choice

What is an amino acid?

• One of 20 different building blocks (legos) that build proteins
• The individual letters of DNA
• a structure inside the nucleus that contains all your genetic material

Multiple Choice

A mutation is defined as:

• A change in the cell's structure

• Anything that changes in an embryo

• A change in the DNA sequence

Multiple Choice

What usually happens to a cell whose DNA has been damaged

• It has trouble manufacturing certain proteins

• It is able to produce twice as many proteins as a normal cell

• It shrinks to half its normal size

Multiple Choice

Which of the following best describes a point mutation?

• A mutation that substitutes one base with another

• A mutation that deletes an entire gene

• A mutation that duplicates a chromosome

Multiple Choice

What mutation has occurred here?

T-G-A-C-C-A

T-G-A-G-C-A

• Substitution/point

• Deletion

• Frameshift

Multiple Choice

What happens to the polypeptide chain during a frameshift mutation?

• It is not affected

• The entire chain is disrupted

• Only the last amino acid is changed

Multiple Choice

Which of the following are possible effects of mutations in gametes?

• They can be passed on to offspring

• They always cause harmful effects

• They never affect traits

Multiple Choice

Which of the following is an example of a beneficial mutation?

• When an organism's lifespan becomes shorter.

• When an organism becomes unable to reproduce.

• When an organism develops immunity to a disease.

Multiple Choice

The survival of a species depends on its ability to adapt to changes in the environment. Which statement correctly describes a way that mutations increase the likelihood that a species will survive in a changing environment?

• Mutations are a source of variation in the species
• Mutations are the cause of disease in the species
• Mutations are not harmful when they occur in somatic cells
