Point mutation Flashcards
Silent mutation= change in codon but
NOT a change in the amino acid
Protein does what
stays the same
A deletion mutation occurs when …..
one or more nitrogen bases are deleted
mutation in a sex cell
changes the sequence of nucleotides in a sperm or an egg cell
A changed gene in a sex cell could become part of the
genetic makeup of the offspring
results of mutations in sex cells
New trait
Structural or functional problems in organism
Death
A mutation in a body cell …
changes the DNA sequence of a particular body cell
Mutations in body cells
are not passed onto offspring
Can affect the genes that control cell cycle causing ….
cancer
Point mutations (substitutions) is a gene ….
gene mutation
Frameshift mutations
Deletion
Addition/Insertion
A point mutation is
a change (substitution) in a base pair in DNA
Change ONE letter and it can change the meaning
of a codon or an entire sequence
A frameshift mutation occurs when…
a nitrogen base is added or deleted in a DNA sequence
Frameshift Mutation causes a
shift in the reading of the codons
