What type of gene mutation has occurred here?
Normal: AGA-TTC-ATA-GCG
Mutant: AGA-TTC-AAT-AGC-G
point
One nucleotide base is changed so only one amino acid is affected.
Substitution Mutation
Point Mutation
Frameshift Mutation
Inverse Mutation
A frameshift mutation where a nucleotide base
is removed from the DNA sequence.
Deletion Mutation
Substitution Mutation
Translocation
Silent Mutation
A mutation is defined as:
A change in the cell's structure
Anything that changes in an embryo
Any change in the physical features of a human
A change in the DNA sequence
Part of a chromosome is repeated
Gene Mutation
Translocation Mutation
Nondisjunction Mutation
Duplication 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.
Cystic Fibrosis
Translocation
Hemophilia
Down Syndrome
__________ is a hereditary disease that affects the lungs and digestive system. The body produces thick and sticky mucus that causes persistent lung infections.
hemophilia
achondroplasia
cystic fibrosis
Huntington's disease
What is Hemophilia?
a medical condition in which the ability of the blood to clot is severely reduced, causing the person to bleed severely from slight injury.
a genetic disorder where there is a 23rd chromosome
a disease where the dystrophin protein is misformed, causing progressive muscle degeneration.
A genetic disorder where there are three copies of chromosome 21
What can cause mutations?
all of these
Mistakes during DNA replication or protein synthesis
Mistakes during mitosis or meiosis
Viruses
