Total questions: 20
Worksheet time: 16mins
A change in a gene, group of genes or chromosome that results in a change in the proteins
Replication
Mutations
Translation
Transcription
A permanent change in the DNA sequence
which can affect a single gene or group of genes
Homeostasis
Somatic Cell
Chromosomal Mutation
Gene Mutation
One nucleotide base is changed so only one amino acid
is affected
Substitution Mutation
Point Mutation
Translocation
Inverse Mutation
A point mutation where one nucleotide base replaces an original nucleotide base
Inversion Mutation
Chromosomal Mutation
Translocation
Substitution Mutation
A substitution mutation that has no effect
on amino acids sequence
Insertion Mutation
Translocation
Silent Mutation
Deletion Mutation
A nucleotide base is inserted or deleted shifting the entire DNA sequence. Entire protein will be changed.
Substitution Mutation
Silent Mutation
Frameshift Mutation
Translocation
A frameshift mutation where a nucleotide base
is removed from the DNA sequence.
Deletion Mutation
Substitution Mutation
Translocation
Silent Mutation
Mutations that involve parts of or all of
a chromosome
Replication

Crossing Over
Part of a chromosome is repeated
Gene Mutation
Point Mutation

Duplication Mutation
Part of a chromosome is reversed.
Inversion Mutation
Deletion Mutation
Translocation
Point Mutation
Part of one chromosome is transported and attached
to a non-homologous chromosome
Inversion Mutation
Translocation Mutation
Duplication Mutation
Point Mutation
Failure of homologous chromosomes
to separate during meiosis.
Results in gametes with either one extra or one missing chromosome.
Translocation
Nondisjunction
Replication
Transcription
Condition caused by nondisjunction at pair 21 during meiosis.
Individuals have an extra chromosome
at pair 21, or a total of 47 chromosomes.
Also called Trisomy 21.
