Mutations Flashcards
1
Q
Base substitution
A
When one base is substituted for another
2
Q
Nonsense
A
Early termination of process of protein synthesis
3
Q
Missense
A
A codon is altered and produces a different amino acid
4
Q
Silent
A
Those that cause no detectable change
5
Q
Gene rearrangements
A
DNA sequences have deletions, duplications, inversions, and translocations that are often caused by chemical and radioactive agents
6
Q
Deletion/insertion
A
Loss/gain of DNA or a gene; can be the loss/gain of a single base or the loss/gain of an entire gene; very bad because the entire frame of DNA is shifted
7
Q
Duplication
A
Extra copy of genes; usually caused by the unequal crossing over during meiosis or chromosome rearrangements
