Question 1
1.

If a mutation still CREATES a protein, but its function is CHANGED, it is called a

Question 2
2.

When a DELETION or INSERTION of a nitrogenous base occurs as a mutation, the RESULTING change can

Question 3
3.

UNLIKE a frame-shift mutation, a base-pair SUBSTITUTION can

Question 4
4.

Examine the diagram below. What would happen to the amino acid sequence if the structure labeled "C" was deleted?

Question 5
5.

Examine the diagram below. What would happen to the amino acid sequence if the base "Guanine" in the structure labeled "C" was substitutedto the base "Adenine"?

Question 6
6.

Match type of DNA mutation on the left with the definition on the right.

  • deletion
  • insertion
  • substitution
  • a base is removed
  • one base is switched for another
  • a base is added
Question 7
7.

Match the effect of a mutation on the left with the definition on the right.

  • nonsense
  • frameshift
  • silent mutation
  • missense
Question 8
8.

In 1986, a meltdown of a nuclear reactor in the city of Chernobyl, in Ukraine, released highly radioactive chemicals into the atmosphere. As a result, people suffered various forms of cancer because of exposure to these radioactive chemicals. Cancerous cells divide much more often than noncancerous cells and form tumors in the body.

A scientist claims that these cancers were caused by harmful mutations. He wants to make a model to support his claim.

Which statement best describes what the scientist’s model needs to represent in order to support his claim?

Question 9
9.

Mutations always change the DNA.

Question 10
10.

Mutations always change the amino acids.

Question 11
11.

Some mutations have a more severe impact than others.

Question 12
12.

Mutations are just like sci-fi movies and can give people super powers.

What is a mutagen?

Question 18
18.

How do mutations happen spontaneously without any outside influence?

Question 19
19.

Which of the following are types of mutagens?

The amino acid sequence would be entirely different after leucine
creates a non-functioning protein, or doesn't create anything.
the genetic code shifts, resulting in a change of amino acids during translation
has no effect on the amino acid produced during translation
changes a single amino acid that will be produced during translation.
The radioactive chemicals caused structural changes in people’s genes, which changed how proteins functioned in cell division.
The radioactive chemicals polluted people’s food, which changed some people’s ability to digest proteins and caused cancer.
The radioactive chemicals polluted people’s drinking water, which caused cells to divide more quickly in the people’s bodies and form tumors.
