What is the difference between mutations in body cells and gametes?
mutations in gametes cannot be inherited by offspring
mutations in gametes can disrupt normal functions like cell division
mutations in body cells can potentially cause cancer
mutations in body cells can be inherited by offspring

What is a substitution mutation?
when one DNA base is removed from the gene's sequence
when one DNA base is replaced by another within the gene's sequence
when one DNA base is moved from one location to another within the gene's sequence
when one DNA base is added to the gene's sequence
|
What can be the outcome of a substitution mutation?
it may create one of the three stop codons
it may create a codon for a different amino acid
it may create a codon for the same amino acid
all of the above
|
What is a 'silent' mutation?
when a mutation does not affect the protein product or the phenotype
when a mutation causes a significant change in the structure of the protein
when a mutation changes the protein's amino acid sequence
none of the above
|
What is an inversion mutation?
when a segment of DNA becomes detached and then reattaches in the opposite direction
when one or more DNA bases are copied
when a segment of DNA is moved from one chromosome to another
none of the above
|
What is a duplication mutation?
when a segment of DNA becomes detached and then reattaches in the opposite direction
when one or more DNA bases are copied
when a segment of DNA is moved from one chromosome to another
none of the above
|
What is a translocation mutation?
when a segment of DNA becomes detached and then reattaches in the opposite direction
when one or more DNA bases are copied
when a segment of DNA is moved from one chromosome to another
none of the above
|
What is the outcome of a mutation that creates a codon for a different amino acid?
it changes the protein's amino acid sequence and possibly its shape and function
it does not affect the protein product or the phenotype
it prematurely terminates protein synthesis
none of the above
