Chromosome Mutations
What is a chromosome made out of?
DNA (nucleotides)
What type of mutation occurs when a nucleotide is substituted like in the chain below
A - T - A
A - G - A
Point Mutation
During crossing over, some chromosomes can unevenly split, resulting in two of the same genes being on a single chromosome. What is this type of mutation called?
Gene Duplication
A point mutation that causes a nucleotide to be substituted but doesn't change which amino acid is created is called a _________ mutation.
Silent
How is a chromosomal mutation different from a nucleotide mutation?
The chromosome shifts, whereas nucleotide mutation either substitutes, adds, or subtracts nucleotides.
What type of mutation is it if a nucleotide is added or deleted like in the chain below
A - T - A
A - C - T - A
Frameshift mutation
What is the name of a mutation in which two non-homologous chromosomes switch sections?
Translocation
If a point mutation causes a premature stop codon we call this a _________ mutation
Nonsense
When chromosomes split too much or not enough, it results in this type of mutation.
Nondisjunction
When a point mutation causes a change in a single amino acid we call this a ___________ Mutation
Missense
