If a mutation still CREATES a protein, but its function is CHANGED, it is called a
When a DELETION or INSERTION of a nitrogenous base occurs as a mutation, the RESULTING change can

has no effect on the amino acid produced during translation
changes a single amino acid that will be produced during translation.
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?
Mutations always change the DNA.
Mutations always change the amino acids.
Some mutations have a more severe impact than others.
Mutations are just like sci-fi movies and can give people super powers.
What is a mutagen?
How do mutations happen spontaneously without any outside influence?
Which of the following are types of mutagens?
