mutations
| Question | Answer |
|---|---|
| base subunits result in no change of amino acid | silent mutation (point) |
| one amino acid substitutes for another | missense mutation (point) |
| codes for stop codon | nonsence mutation (point) |
| single base pairs may be inserted into or deleted from dna | frame shift mutation (point) |
| single base pairs limited to single genes | point mutation |
| change in position or orientation of dna segment, or cause segment to be lost | chromosomal mutation |
| remove part of genetic material | deletions |
| arise if homologous chromosomes broke at different positions and reconnected to the wrong partners | duplications |
| a segment of dna may be removed and reinserted into the same location in the chromosome but flipped | inversions |
| segment of dna breaks off, moves from its chromosome, and is inserted into a different chromosome | translocation |
| permanent changes in the genetic material that occur w/o outside influences | spontaneous mutations |
| agent outside the cell causes a permanent change in dna | induced mutations |
