Mutations Quiz

Which of the following are a type of point mutation?

• substitution

• insertion

• deletion

• frameshift

What effect does a harmful mutation have?

• decreases chances of survival

• increases chances of survival

• decreases likelihood to developing cancer

• increase unique abilities

What effect do helpful mutations have?

• decrease chances of survival

• allows evolution to occur, and provides genetic diversity

• decreases likelihood of cancer

• hinders activity

What is the definition of a DNA mutation?

• the original DNA sequence

• a strand with 7 strands

• heritable changes in genetic information

• the hydrogen bonds turning into covalent bonds in the DNA strand.

This type of substitution mutation adds code for a stop codon

• silent

• missense

• nonsense

• deletion

This type of substitution mutation changes only one amino acid that's being coded for by the DNA sequence.

• silent

• missense

• nonsense

• insertion

This types of substitution changes one base in the DNA code, but does not change any translated amino acids or the resulting protein.

• silent

• missense

• nonsense

• inversion

If a base is missing (deletion) or an extra base is present (insertion) at the end of the mutated DNA and all the amino acids have changed, what type of mutation occurred?

• frameshift

• point

• silent

• missense

Which type of mutation is MOST LIKELY to cause the greatest disruption by altering the most amino acids and thus changing the protein shape the most?

• Frameshift

• Point

• Silent

• Missense

Which of the following are mutagenic factors (causes mutations)?

• Tanning (UV rays)

• Pollutants (smog, CO2, factory output)

• Chemicals we smoke (vaping) or eat (pesticides, additives).

• All of the above
