Mutation Biology Questions With All Correct Answers
Mutation correct answer -a change in the genetic material of a cell; cause
by a mistake during DNA replication.
Gene Mutations correct answer -changes to a single gene.
Point Mutations - involve changes in one or a few nucleotides/bases. correct
answer -involve changes in one or a few nucleotides/bases.
Substitutions correct answer -one base is changed to a different base (May
or may not affect the amino acid).
Insertions correct answer -adds a new base to the DNA sequence
Deletions correct answer -removes a base from the DNA sequence
Frameshift Mutation correct answer -caused by insertions and deletions
that changes the reading sequence.
Usually causes a change in the amino acid sequence.
Missense correct answer -point mutation in which a single nucleotide
change results in a codon that codes for a different amino acid.
ex: Sickle Cell Anemia and ALS (Lou Gehrig's Disease)
Nonsense correct answer -codon which codes for a premature stop codon.
ex: Muscular Dystrophy and Cystic Fibrosis
Chromosomal mutation correct answer -change in the number or
structure of a chromosome.
Change the location of genes on a chromosome
Change the number of copies of genes.
Deletion
Duplication
Inversion
Translocation correct answer -What are the four chromosomal mutations?
