Which of the following is not a mutagen?

A. sulfur dioxide

B. UV rays

C. X-ray machines

D. bacterial infections


Some mutations may be beneficial in some environmental contexts and detrimental in others.

A. TRUE

B. FALSE


This type of mutation results in the addition of one or more nucleotides in a gene.

A. deletion

B. insertion

C. substitution

D. frameshift


This type of mutation results in there being part of all of an additional or missing copy of a chromosome.

A. deletion

B. inversion

C. translocation

D. nondisjunction

E. addition


If a mutation affects only a single protein, it is known as a

A. gene mutation

B. chromosome mutation


This type of mutation results in the removal of all or part of a chromosome.

A. deletion

B. inversion

C. translocation

D. nondisjunction

E. addition


This kind of mutation means the protein is still produced, but appears and functions differently.

A. missense

B. nonsense

C. neutral

D. silent


This type of mutation results in part of the chromosome being attached in reverse order/the other way around.

A. deletion

B. inversion

C. translocation

D. nondisjunction

E. addition


This type of mutation results in the removal of one or more nucleotides in a gene.

A. deletion

B. insertion

C. substitution

D. frameshift


This type of mutation results in the full sequence after the mutation changing, causing a completely different set of amino acids to be produced.

A. deletion

B. insertion

C. substitution

D. frameshift


This kind of mutation means the protein is still produced and while the amino acid sequence has changed, the function of the protein is not affected.

A. missense

B. nonsense

C. neutral

D. silent


It is possible for variation to occur without mutations.

A. TRUE

B. FALSE


If a mutation affects a large part of a chromosome or a large number of genes, it is known as a

A. gene mutation

B. chromosome mutation


All mutations are detrimental.

A. TRUE

B. FALSE


This kind of mutation means the protein looks and functions identically to the non-mutated version, as the amino acid sequence has not changed.

A. missense

B. nonsense

C. neutral

D. silent


This type of mutation results in there being an extra part of a chromosome.

A. deletion

B. inversion

C. translocation

D. nondisjunction

E. addition


This type of mutation results in part of one chromosome reattaching to a different chromosome (e.g. part of chromosome 2 attaches to chromosome 6)

A. deletion

B. inversion

C. translocation

D. nondisjunction

E. addition


This type of mutation results in the switch of one or more nucleotides into (a) different nucleotide(s) in a gene.

A. deletion

B. insertion

C. substitution

D. frameshift


This kind of mutation means the protein is not produced after the mutation point due to the introduction of a “STOP” codon.

A. missense

B. nonsense

C. neutral

D. silent
