QUIZ - Unit 5 Lesson 11 (Genetic Mutations)

A mutation is

• The total number of possible alleles for a single gene

• any change in DNA, the genetic material of a cell

• any change in a gene that is passed from parent to offspring

• any change to the appearance of an organism over time

What might happen when a gene gets a mutation that changes the structure of a protein?

• the function of the protein could change

• the protein could make multiple copies of itself

• the cell that the protein is in could grow stronger

• the protein could change into an earlier opy of protein

How does a cell usually respond to a mutation in a gene?

• the cell completly changes its function

• the cell never respongs to a mutated gene

• the cell repairs the mutated gene

• the cell dies as a result of the mutation

What might happen when a mutation occurs outside of a gene?

• Mutations that occr outside of a gene cannot be repaired

• mutations that occur outside of gene are likey to spread to the gene

• mutations that occur outside of a gene are most likey to affect several traits

• mutations that occut outside of a gene will most likey not afect any traits

When is a mutation most likely to occur?

• when a cell is newly formed

• when a cell is proparing to die

• when a cell is preparing to diviide

• when a cell is in the process of reparing damage

What is a mutagen?

• a cell that is causing other cells to muate

• a protein or other cell structure that has mutation

• anything in the environment that causes a change in DNA

• anything in the cell that causes a change during cell division

Which of these is NOT likey to be a mutagen?

• a virus

• UV radiation

• car exhaust

• a damaged cell

What happens to cells when an orgaism gets cancer?

• The cells die

• The cells divide uncontrollably

• the cells starts to lose proteins

• the cell start to become organs

What happens when a mutation is consirdered to be neutral?

• The mutation does not negatively impact the organism's survival

• the mutations will definitely be passed form parent to offspring

• the mutation is between a postive and negtive mutations on the same gene

• the mutation cannot be repaired

What happens to an organism when it has a harmful mutation?

• the organism will pass the mutation onto its offspring

• the organism woll start to harm other organisms

• the organism will have a harder time surviving or reproducing

• the orgaism will get mildy sick for a short period of time
