MULTIPLE SELECT QUESTION
45 sec • 1 pt
An organism is exposed to a mutagen, such as X-rays or ultraviolet light.
What could be the effect of the mutagen on the organism?
Select all of the
answers that apply.
The mutagen may disrupt gene function to the harm of the organism.
The mutagen may change gene function in a way that benefits the organism.
The mutagen may change the genetic material of the cell from DNA to
proteins.
The mutagen may have little or no observable effect on the organism.
Answer explanation
Mutagens can disrupt gene function, change gene function (potentially beneficially), or have little to no observable effect on the organism.

MULTIPLE CHOICE QUESTION

What are considered "positive" mutations?
mutations in the DNA sequence that changes the resulting protein and harms the organism
mutations in the DNA sequence that changes the resulting protein and benefits the organism
mutations in the DNA sequence that produces the same protein
all mutations are considered bad and harm the organisms
Answer explanation
Positive mutations are those in the DNA sequence that change the resulting protein and benefit the organism, rather than harm it.

MULTIPLE CHOICE QUESTION

What are considered "negative" mutations?
mutations in the DNA sequence that changes the resulting protein/outcome that harms the organism
mutations in the DNA sequence that changes the resulting protein/ outcome that benefits the organism
mutations in the DNA sequence that produces the same protein/ outcome
all mutations are considered bad and harm the organisms
Answer explanation
Negative mutations are changes in the DNA sequence that result in harmful outcomes for the organism, such as altering proteins in a detrimental way.

MULTIPLE CHOICE QUESTION
45 sec • 1 pt
Original DNA = TAC GAC TTG AAT
Mutated DNA = TAC ACT TGA AT
What type of mutation has occurred?
Chromosomal mutation
Point mutation
Frameshift mutation due to addition of base
Frameshift mutation due to deletion of base
Answer explanation
The type of mutation that has occurred is a frameshift mutation due to the deletion of a base, causing a shift in the reading frame of the DNA sequence.

What type of chromosomal mutation occurred?
chromosomal insertion/duplication
chromosomal deletion
chromosomal inversion
chromosomal translocation
Answer explanation
The correct type of chromosomal mutation that occurred is chromosomal inversion, where a segment of the chromosome is reversed in orientation.
