Mutation Flashcards
What are mutations
changes in the genetic material of the cell
what are point mutations and what can it do
changes in just one base pair of a gene
can lead to the wrong amino acid being made
types of point mutations
base pair substitutions
base pair deletions and insertions
What is a base pair substitution
One base pair is replaced by another
ex
AGTTA
TCAAT
to
AATTA
TTAAT
Mutation that doesn’t have an effect because of the redundancy of the genetic code
Silent mutation
Will code for an amino acid just not the same one
missense mutation
Will code for a stop codon, almost always makes a non functional protein
nonsense mutation
What is insertion and deletion
Adding an extra base pair
or taking away a base pair
they have a disastrous effect more often than substitutions
What causes a frameshift mutation
Insertion and deletion mutation
